There is certainly the Visitor design pattern, but that's intrusive and
that doesn't provide generic visitation.

If you want to compute something on a string at compile-time, you need a
Here, it is needed to mangle the possibles names at compile-time and
build an automaton to recognize the mangled name RTTI provides.
With a regular string, you would have to mangle the name at runtime,
then do a linear search within the possible cases.
