Well, that seems sort of theoretical to me.  But I agree that in theory
it is possible.

Of course, we then would require a way to name either a complete set of
overloads or a specific overload.  I suppose the easiest way to do that
would be to permit a regexp, and compare it against the full demangled
name.  Is the full demangled name readily available?  cc1 doesn't
currently use regexes, but the gcc driver does, and the libiberty
support is not large.

Or I'm willing to let this option die, and be replaced by a plugin.  I
wanted to object to letting it die because there is a different way to
do something different.  That doesn't seem like an appropriate way to do
things.
