Yes it was. But in the fairly dominant C-family languages in use it has become widespread so we have to adjust to it.

I will shoot on sight anyone who uses case sensitivity so that they can have symbols that vary only by case. Case sensitivity was a bad idea in the first place.

Case in point.
We have an enum type in one IDL file and an enum member in another IDL file, both with the same spelling. Each has different case, however.
Do you think the MIDL compiler can tell them apart - NOT 
Distinguishing a variable from a type purely onc ase has always been a very bad idea to me too

I wouldn't do it in anything other than the scope of a method, where the context should be simple enough to differentiate using case alone. Providing everyone else is playing by the same rules in other scopes of course

lol
the other day, parsing along the lines... ran into something funny...
2 separate modules, module A and B
A had a method called CmdDoSomethingCool and the other module had a const int named,..guess what... CmdDoSomethingCool.
Only problem, a file from module A was included in module B, and if not included in the right order, well... sometimes it would actually compile but crash in runtime and sometimes, it wouldnt even compile...
Those pricks (sorry 'bout that) who wrote the code should be deported to another planet!!!!!
That and code that reads something like:
*p = GetPointer()
if (NULL==p)
UsePointer(p)
I found those lines all over the place.... and then they wonder why the heck it crashes.... lol
I think the poor chap who wrote the code was a victim of Copy'N'Waste...

Is better in my opinion than
public void Stuff()
{
ThingAmiBob MyThingAmiBob = new ThingAmiBob();
}
I think it's generally considered bad style to have an instance variable name that differs from its type name only in case. A type name represents the name of... well, a type! When creating an instance of a type, the instance name should be specific enough to differentiate it from other instances of the same type, as well as from the type itself, for that matter.
There are times when it is tempting to break this rule. For example, say you are passing a timer to a method:
public void SomeMethod(Timer timer)
{
}
The context could be general enough till it becomes difficult to think up a name for the parameter that somehow distinquishes it from its type. The purpose of the method may give us a clue, though, and we could rename the parameter something like pollingTimer, or whatever. Sometimes its kinda tough, and you may wind up just naming the parameter t or tmr, if you want to strictly avoid having a variable name differ from its type name only in case. But that may not be any better.
So my question for everyone is what would you do in the above situation when it just isn't clear what a parameter should be named?

Agreed, in most circumstances it is - but in others the typename is an obivous, easily understood choice. When a single instance of a class is required in a method, and that class has a descriptive name I don't see the point of naming it "myCustomer" or "theIndexer" or "aDirectory" or "tickyTimer".

Camel cased typename , if further classfing the parameter is redundant - which it is in the Timer example. DoStuffWithTimer(Timer aTimerToDoStuffWith) is a tad pointless IMHO when the type is descriptive and distinct.
World isn't going to burn with either method though

Well, it is the style of the Standard Library, so if you are using it a lot (we do at my work) it makes sense to adopt it. Back in the days I was using MFC more, Hungarian notation was a natural choice.

I disagree. I find it harder to type. However, from a readability point of view it is superior to Camel and Pascal case. It is also the Eiffel house style and if I ever get to do Eiffel I would fall in with it and probably get used to it too.

The question was about "local" variables.
Not members, statics etc...

hmm.. you got point.
I thought local was meant to be method-body-local....
But how about assembly local and program local then... is a class local to it's assembly?
(just a joke...)

Actually, it's a good question, and sort of points out the arbitrary qualities of coding styles. You say toehmahtoe, I say toemaytoe.

I meant local variables, as in "local variables to a routine", not "local fields to a class".
Everytime I write one of these polls I feel I should consult counsel to ensure I've covered everything. When polls start with "WHEREAS..." you know I've finally cracked.

"Method variables" would have worked for me. I have to admint I misunderstood the poll as asking about "Class variables" (well actually, "fields" in C#).
Now that I know what the poll is asking, I have to say I'd fire anyone that didn't respond with camelCasing

Hmm. I still use the m_ prefix for dialog box DDX variables, as sort of a 'mini-convention' within a dialog class. It makes it easier to differentiate the variables that are used for 'dialog data exchange' from others.
