I'm not sure if the following is relevant, but I found it in

Would it be helpful to reserve a leading character (say, "*") that means
that strcmp should not apply, but rather pointer identity? Thus a class
foo that is intended to be local, as opposed to forced local via
RTLD_LOCAL, can just use "*foo" and not have to bother with mangling?
