struct Foo
{
     property bool isOne() { return true; }
}

struct Bar
{
    Foo foo;
    alias foo this;
    alias isOne isTwo;
}

void main() { }

test.d(10): Error: undefined identifier isOne

Essentially I wanted to partially merge two types which had a similar
structure, but I still wanted to keep the different APIs. I can use property
getters and setters to forward a function, but I thought an alias would help me
more by allowing me to alias a symbol that was going to be merged via the alias
this feature.

So while it's not crucially important, I'm making this a feature request.
