It occurs to me that it would be extremely powerful to be able to do something
like:

alias SomeClass.* *;

and pull in all the methods of that class into the current scope. Uses for
this:

Proxy classes

class Proxy(T)
{
  ...
	alias T.* *;
}

More powerful mixins:

template Foo(T)
{
	alias T.* *;
}

class Mixed
{
  SomeClass X;
	mixin Foo!(X);
	this() { X = new SomeClass; }
}

Of course, it would be even simpler and more powerful if mixins had
constructors... But that rant is already somewhere ;)

I know this approaches the "accidental inclusion of a compile-time functional
language", but this would be incredibly powerful. One thought that comes to
mind: this probably should not pull in operator overloads and such, only
regular methods.

Thoughts?
