I thought about that, too. This is a good idea, but it's also too
compiler-specific and somewhat error-prone.
I also thought about some Mangler template, which is capable of generating
a mangled name for a given function at compile time, and using it instead
of some pre-generated string.
This is a more generic solution, one could substitute different manglers
for different compiler vendors.
In this case, I could "typedef uint unsigned_long;" and my mangler would
recognize unsigned_long and mangle it differently from uint.
Just an idea...
