Sorry, Ctrl-S was meant for emacs, not for the mailer ;-)

Anyway, name mangling will not be standardized. Even better: it is not
allowed for different C++ compilers to have the same name mangling! Why?
Because of the implementation. If two compilers implement
overloading/classes/templates different while having the same style of
name mangling, your program would still link, but things would go terribly
wrong when you run it. Therefore, it is mandatory that C++ compilers have
their own name mangling style.
