I think this is an interesting idea, but perhaps a bug report isn't the
right venue for it? Did you take this up on emacs-devel?
(And here's my two pennies on the subject after considering it for about

that useful... If we want a more expressive type system in Emacs, this
is the wrong place to start.)
