One thing I've always wanted to do is cross reference the data structures/containers for various languages. In Python a dictionary is what Perl calls a hash and what C++ calls a map. Three different names for the same data structure (key value based).
I don't think Perl has a set container by default, but they can be added from CPAN, Python does, it's called a set ;) as does c++ where it, too, is called a set. Again, a key value based data structure, but in this case, the key is the value.
