Bug 9838 – Allow calling aliased method on an object

I could really use this feature in D: auto callFunc(alias func, Class)(Class object) { func(object); // ok } auto callMeth(alias meth, Class)(Class object) { object.meth(); // denied } void foo(C c) { } class C { void foo() { } } void main() { C c = new C; callFunc!(foo)(c); callMeth!(C.foo)(c); } The benefit here is that we won't have to use __traits(identifier, meth), and especially won't have to use a string mixin. For example to make the above work properly one has to write: import std.string; auto callMeth(alias meth, Class)(Class object) { mixin(format("object.%s();", __traits(identifier, meth))); } Or you can use string appending, pick your poison. It's very ugly, even if you decide to use q{}. String mixins are generally very error-prone and hard to debug, this feature would alleviate that.

This is asking for too much magic. At best it should be a DIP, but I don't think we should go there.
