// The CFA name mangling scheme is based closely on the itanium C++ name mangling scheme, with the following key differences:
// * Variable names are also mangled to include type information, not just functions
// * CFA does not have template expansion, so the rules for function specialization do not apply.
// * CFA instead has to handle type parameters and assertion parameters.
// * Currently name compression is not implemented.
