>Dealing with the fact that a list is a null-terminated linked list instead of an actual sequence/vector/tree is a big deal. If you need a vector, just use a vector, don't use a list. Common Lisp has very flexible vectors and arrays. Lists are the way they are because they're the fundamental block for manipulating/constructing lisp code itself. >Common Lisp has a notoriously fickle and opaque system for importing other code into your space. Care to elaborate? You just load it; everything is in its own, separate namespace.
