Unfortunately the biggest problem is due to AutoLisp not evolving as the other branches of Lisp has. It was originally taken from XLisp in the mid 80's and has not grown (in Lisp terms) at all. E.g. it has no object orientation as Common Lisp has; no way of defining optional arguments to a function; ratio / complex / vector / structure / hash table / class data types aren't included; many standard functions aren't available (e.g. floor, ceiling, round); etc. Never mind added library access like DotNet (or even direct ObjectARX) ... the only thing ADesk deemed important enough was ActiveX, but only because someone else already did it for them: when Vital Lisp added these in the 90's, ADesk purchased it and renamed it to Visual Lisp.

in  2011 the last update for autolisp is the new programming language  C++LISP
