medo-bear, you might want to know that you appear to be shadowbanned -- all your comments for the last ~10 days are dead. (I have some plausible guesses at what provoked this, though I have to say that I didn't see anything that looks to me like sufficient justification.)
(I "vouched" for your comment to which this is a reply, and that seems to have been sufficient to un-dead it. Unless the system's set up so that vouching for a shadowbanned comment un-deads it only for the person who does the vouching, I guess...)
SBCL, which is a very popular Common Lisp implementation, is indeed strongly typed. Coalton, which is an addon, is even statically typed
