And what's the logic behind this:
class Test

int f() { return 10; }
static assert(is(typeof(&typeof(this).f) == int function())); // huh?
static void t()

// as expected:
f(); // error : need 'this' for 'f' of type 'int()'
// calling a method without a context pointer...
auto x = &f;
x(); // call the method with no context pointer, how is this okay?
pragma(msg, typeof(x)); // prints: int function()
}
}
If f() were supplied an argument, the function would receive the first
arg as the context pointer, and the rest would be out by 1! O_o
I don't see how this code can be acceptable?
If such a thing (getting a static function pointer from a delegate)
were to be supported, surely: is(typeof(&Test.f) == int
function(Test)), though this is only valid for some (most) abi's.
This is a known issue: https://issues.dlang.org/show_bug.cgi?id=3720
(What I do is: typeof(&typeof(this).f) is int delegate(), but auto x =
&f does not compile as the 'this' reference is missing.)
