I want to get a mangled name of a D function by `core.demangle.mangle`, but I'm in trouble because there are no ways to express a type of a function, which is used for a template argument of `mangle`.

For example, it is wrong to use the type `int function(int,int)` to express the type of `int add(int,int)`.

Because it expresses the type of a function POINTER, not just a function.

The fuction name in a binary compiled this function is "_D3addFiiZi", but `mangle!(int function(int,int))("add")` returns "_D3addPFiiZi", which includes "P" meaning POINTER.

How can I get the former one?

Thanks.

typeof works:

import core.demangle;

int add(int, int);

void main() {
  alias F = typeof(add);
  pragma(msg, mangle!F("add"));
}
