The following alias declaration is totally legal but actually it's not usable

---
class Foo
{
    void something(size_t param){}
}

class Bar
{
    private Foo foo;
    this(){foo = new Foo;}
    alias somethingelse = foo.something;
}

void main(string[] args)
{
    auto bar = new Bar;
    //bar.somethingelse(0u);
}
---

The call doesn't work but the declaration is fine. What is possible to make with this declaration ?

I believe it currently just does the same thing as:

---
class Foo{
	void something(size_t param){}
}

class Bar{
    private Foo foo;
    this(){foo = new Foo;}
    alias somethingelse = typeof(foo).something;
}

But IMO the appropriate response here is to just make it work as one would expect, not to make it illegal.
