Rosetta Code

So there's this site Rosetta Code that shows snippets of how to do Task X in lots of different languages. I find that pretty fascinating from the semantic-programming standpoint; in a certain sense, each set of solutions encodes the same thing, the same meaning.

The link goes to "open a window"; Perl has five ways of doing it, depending on the GUI framework you're using, and I'd like to explore that parallelism in Decl.
