there are at least a few of us that are VERY interested. some of us just spend loads of time reading and poking around with things while we're learning about them instead of commenting or asking questions.
as far as how the perl interfaces to c++ are implemented, i couldn't agree more. there are a number of functions that could be consolidated, expanded upon, moved, or just corrected.
for example... the functionality of Mob::EntityVariableExists, Mob::GetEntityVariable, and Mob::SetEntityVariable could be combined into Mob::EntityVariable(evName, [evValue]), and it would be assumed that we wanted to return the value (evValue) of the variable name (evName) if no value was passed. there are tons of other things like that and and the ones you covered that i've been puttering around with to see what i can come up with on my personal server.
i also realize that once things are implemented and used a bit, it's difficult to want to change them for everyone because of migration issues. do you leave the old code in there for a while until people get a chance to move it, or you just yank it out unceremoniously?
