This doesn't avoid the name mangling problem:

-------------------------------------------
module A;
struct S(alias F)
{
    static immutable string s = F.mangleof;
}
-------------------------------------------
module B;
S!(a => a) foo;
-------------------------------------------
module C;
S!(a => a) bar;
-------------------------------------------

If I've understood correctly, you want foo and bar to be of the same type, but
they can't be because the static s member must have a different value for each
type.
