This code fails on the line 'int b = f;'. Is it supposed to?
I think so.
'alias this' is used to forward stuff that appears to the right of a dot
onto the named member.
In c++ to get what you are doing to work, you'd add a customer cast
operator:

but I'm not sure how the cast operator overloading works in D, I don't
know if it will try to implicitly cast and call your operator.
