'catch' is a reserved word, used in exception handling.

It allows for a function to abort processing in case of an error, in a safe manner.

When an exception is thrown, objects on the stack are properly unwound and their destructors called. The appropriate catch statement in the try / catch block is then executed to handle the error.

Please see:
http://en.wikipedia.org/wiki/Structured_exception_handling[^].

This is one of the most fundamental and important inventions in programming of all times and peoples, mostly pioneered by Barbara Liskov at al (http://en.wikipedia.org/wiki/Barbara_Liskov[^]).

Today, anyone using any imperative of functional programming but not using or understanding this part of technology cannot be considered as a software developer, software engineer or a programmer. Not in any sense. Never. Not in any circumstances. Learn it now. Learn it very well. No excuses. This is not hard to learn.
