I know of several big name games that use Lua (A little game called World of Warcraft comes to mind, you may have heard of it) however none that use Perl.

I am however also working (ailbet slowly) on a C++ library to bind subs/functions/methods/whathaveyou from a scripted language's namespace to a C++ object or class. I'm still working out the C++ side of the interface but the first implementation language is going to be my native Perl. Implementations in Lua, Python, and Ruby are also planned, but they'll come after I have a working system that uses Perl (As an aside, I am aware that perl is considered by many one of the hardest languages to embed. I figure if it can work, the others will be much easier.)

I don't have a blog or website or anything that I post changes to, though I suppose I'll end up making one before this gets released.
