I've twiddled with a number of AI algorithms, not necessarily in perl, but there's a lot going for perl in this area, specifically the fact that most AI's are not normal thought of in terms of interactions with the OS to any great extent, and using perl allows this interaction to occur. (Not that other languages can't do this, but perl makes the process much easier). This allows for more interesting uses of perl and AI; for example, I am attempting to develop a rules-based system that can be used as a possible backend of a socket connection for business logic. The possiblities are , of course, endless.
