It's Perl that I associate with mixing lexicals ("my") and dynamics ("local") without a naming convention (or full separate namespace). islisp's dynamic-let/dynamic etc. was cleaner than common lisp's approach. Probably backward compat is too much of a concern to make that feasible for emacs lisp though (cl presumably had similar backward compat concerns...).
