Hidden Features of Perl, PHP, JavaScript, C, C++, C#, Java, Ruby, Python and others. I've learned things from the C, C++ and Perl pages.

Hmm. I'm not impressed with the "hiddenness" of some of these allegedly hidden features on the Perl page. Three in particular I checked at random are not especially obscure:
- use of qw() - chaining || for multiple-choice evaluation - use strict
Is it really hidden to say that 'use strict' is a good thing? I don't think I've written a Perl script that didn't have 'use strict' in the boilerplate at the top for over a decade.
I guess I was hoping for really esoteric, undocumented stuff, not tips-n-tricks stuff.

The C and Objective-C ones were pretty pedestrian. Most times I wander over into Stack Overflow, it's a mass of "do my homework for me" questions.
