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.
