--- Comment #1 from Simen Kjaeraas <simen.kjaras@gmail.com> ---
An alias is not a real identifier - thinks of it more as like a pointer to the real identifier. This can be verified by doing the exact same as you did in main.d, in mod.d:

auto identity(T)(T t) { return t; }
alias identityInt = identity!int;
static assert(__traits(identifier, identityInt) == "identity");
