Perl has hashes, which are close to Python dictionaries. Tuples don't differ
significantly from arrays, except in their immutability. Perlmongers would
probably say that Perl allows for quick prototyping, and I couldn't
disagree. In my opinion it's Perl's excessive brevity that limits its
usefulness. Clearly it's a popular language with many satisfied users.

The speed issue usually isn't an issue, and when it is then it's easier to
incorporate C and C++ code into Python than Perl, I believe. As the author
of one of the *many* Python books now availabe (OK, not as many as Perl, but
the situation is incomparably better than it was two years ago), I think you
underestimate the strength of the current literature.

This hardly matters. If the numerical value of releases really meant
anything then it might be an indicator, but compare Python 2.2 with a
comparably-numbered Perl release and see what you think. Perl 4 introduced
much that people now think of as "classic" Perl.

and, of course, it was!
