Not being a C++ programmer, I didn't know something like that would
work; I kinda like it.

The suggestion I had been about to post was

   mangle_type(foo, typename)
   mangle_type("bar", typename)

where the first argument can be either an identifier or a string,
and typename can be anything that names a type, e.g. a typedef or
template argument or suchlike.

The idea being the string/identifier would be used as the base
name of the function, with the rest of the goop coming from the
given type.  One could then create mangled names that don't
correspond to any function declaration in scope.
