I am curious about the answer myself but there is the workaround of
passing the overload through a lambda:
import std.traits;
int foo(long)
{
return 0;
}
short foo(byte)
{
return 0;
}
void main()
{
static assert(is (ReturnType!(() => foo(long.init)) == int));
static assert(is (ReturnType!(() => foo(byte.init)) == short));
}
