Because one of the points of a parser generator is having both of those things.
*sigh*
It's not really complete without error recovery
Still, I was looking, and I see Gold Parser's parser doesn't do error recovery either.
It's not right though. It's just not right.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

Reading thru The Mythical Man Month and there are quite a few interesting items.
Gutless Estimating
Observe that for the programmer, as for the chef, the urgency of the patron may govern the scheduled completion of the task, but it cannot govern the actual completion.
An omelette, promised in two minutes, may appear to be progressing nicely. But when it has not set in two minutes, the customer has two choices --- wait or eat it raw. Software customers have had the same choices.
The cook has another choice; he can turn up the heat. The result is often an omelette nothing can save --— burned in one part, raw in another.
Now I do not think software managers have less inherent courage and firmness than chefs, nor than other engineering managers. But false scheduling to match the patron's desired date is much more common in our discipline than elsewhere in engineering.
It is very difficult to make a vigorous, plausible, and job-risking defense of an estimate that is derived by no quantitative method, supported by little data, and certified chiefly by the hunches of the managers.
Clearly two solutions are needed. We need to develop and publicize productivity figures, bug-incidence figures, estimating rules, and so on. The whole profession can only profit from sharing such data. Until estimating is on a sounder basis, individual managers will need to stiffen their backbones and defend their estimates with the assurance that their poor hunches are better than wish-derived estimates.
I'm pretty sure that estimating hasn't changed at all since this was originally written (1982 or so).

And like an omelette, you have to break a few eggs to get the job done.

And just un-like an omelette, the software job is never, ever done

Surely you keep your omelette up to date with the latest frying pans and optional herbs and spices?

...and if you rush the chicken to produce eggs quicker, you'll end up with a burnt out chicken before long.
I'm sure plenty more valid analogies can be added. C'mon CP, don't let me down...

The chicken stops every six inches while it walks across the road (these are 'sprints'). It verifies with the stakeholder (aka the farmer) at each point that he's getting what he wants, i.e. the chicken across the road. The farmer can adjust the chicken's route any time he likes.
Of course, none of the principals notice the traffic on the road...

That's easy. Use git for source control so that nobody really understands what a 'commit' does.

And yet sales keeps telling the customers that the company has a golden goose.

Yeah, you are correct that the original Mythical Man Month was written in 1975 but I wasn't sure if this was part of the original or the revision (1982) so I guessed the latter so I woudln't make it sound too old.

Same people who figured they could take 9 women and have a baby in one month.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.
