Is there an alternative I can use?

It expects the parent and the name rather than an instance of the 
function.

Try

__traits(getOverloads, __traits(parent, fn), __traits(identifier, 
fn));


Which is just long-hand for like

__traits(getOverloads, mymodule.name, "fn")

So, for example:

---
void fn() {}
void fn(int) {}
void fn(string) {}

void main() {
	foreach(overload; __traits(getOverloads, __traits(parent, fn), 
__traits(identifier, fn))) {
		pragma(msg, typeof(overload));
	}
}
