As an aside, I've long wanted to add anonymous faces to Emacs; a cursory investigation suggests that simply allowing lisp `face vectors' to be used in a few places (skipping the name->vector lookup) would actually work. However the huge amount of backward-compatibility hair in Emacs' face machinery always makes such things a bit touch-n-go... [I don't think the name lookup efficiency is actually much of an issue though; my reason is more to avoid the necessity of naming faces.] -Miles -- I'd rather be consing.
