Wow! This is terrific.

These are easy, just a matter of finding these.

Yes. I can probably help with this.

Likewise.

This is tricky. I have an object factory that needs to do this as well
and I have compiler-specific mangle/demangle code that deals with this.
Obviously, it only works with the compilers I have mangling specs for.

Once you have the new tar file, please drop me a line (I'm not on the
maintainers list), and I'll see how I can help.
