     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.
