Linking languages

Question

I asked a question earlier about which language to use for an AI prototype. The consensus seemed to be that if I want it to be fast, I need to use a language like Java or C+

Answer 1

Perl has several ways to use other languages. Look at the Inline:: family of modules on CPAN. Following the advice from others in this question, I'd write the whole thing in a single dynamic language (Perl, Python, Ruby, etc) and then optimize the bits that need it. With Perl and Inline:: you can optimize in C, C++, or Java. Or you could look at AI::Prolog which allows you to embed Prolog for AI/Logic programming.
