Hidden Features

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.

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.

From the comments:

I've always found Perl itself to be a hidden feature. ;) – Paul Nathan Apr 16 at 14:00

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.

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
