isCallable and templates

[Steven Schveighoffer via Digitalmars-d-learn]

Consider:

import std.traits;
class Foo
{
    void bar() {}
    void baz()() {}
}

This works:

static assert(isCallable!(Foo.bar));

This does not:

static assert(isCallable!(Foo.baz));

However, clearly I can call baz due to IFTI (with the equivalent syntax, 
someFoo.baz() or someFoo.baz). Is there a way to fix this?
