Bug 2438 – Cannot get types of delegate properties

alias void delegate() Dg; alias typeof(Dg.ptr) Ptr; alias typeof(Dg.funcptr) Funcptr; ---- test.d(13): Error: argument void* to typeof is not an expression test.d(13): Error: argument void* to typeof is not an expression test.d(14): Error: void delegate() is not an lvalue Worked around by defining an intermediate delegate instance: alias void delegate() Dg; Dg dummy; alias typeof(dummy.ptr) Ptr; alias typeof(dummy.funcptr) Funcptr;

Not that I don't think it's a bug, but - what the heck? I honestly can't tell what Dg.ptr is. The compiler doesn't accept it as a type, but it also doesn't accept it as an expression. Dg.ptr.stringof gives "void*", as if it's a type. I'm kind of surprised that you can access it at all. Also, another workaround is to use typeof(Dg.init.ptr/funcptr).

typeof(Dg.init.funcptr) fails: Error: null is not an lvalue BTW, typeof((int[]).ptr) works as expected
