It's probably not hard to fix: but it'll take us time and energy for
a feature that nobody has ever used.  And the fix will probably make the
code a bit more complex, require a few more fields in some structure,
etc...

I simply think we should move in the direction of dropping frame-local
variables in favor of something else.  A first step in that direction is to
disallow the more complex aspects of frame-local variables which have never
been used and thus do not deserve to be supported.
