Indeed, the lexbind branch is not meant to solve those problems, I just
turned the special form into a macro, preserving all the (mis)behavior
as best as I could.  I just pointed out that that branch (which should
be merged soon) has already started to move with-output-to-temp-buffer
to Elisp, so we don't get conflicting changes on this front.
