+// 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.
