Yeah, it is the #1 time user and #1 space user :-)

I think whatever problems we have here will be exaggerated by
multi-exec, too.

Types also are not globally visible and create no ELF symbols.  So, I
think you need an additional argument about why enum constants ought to
be treated differently.

Also, I will occasionally start gdb just to "print/d CONSTANT" to see
what its value is.  So this would be another user-visible change -- we'd
require a full debuginfo scan on any expression.  (Though it occurs to
me that perhaps this is happening due to some "static scope" set at main
or something ... I did not check.  If so that would eliminate this
objection to this particular bit.)

Me too.
