inverse of std.demangle?

[Timothee Cour]

Thanks much, that's a good start.
Template support would definitely be needed as it's so common.
This should go in std.demangle (or maybe a new std.mangle)

* One use case is using it in shared libraries:
user asks for a symbol via its demangled string representation (which is
most natural for user), then the string is mangled, and then calls dlsym to
retrieve the actual pointer to symbol in the shared lib.
* Another is in REPL where we can optimize certain calls by bypassing the
compiler, when the symbol already exists in main executable.
* There are other use cases

So this is worth doing.
