So then in theory
Variant v;

Meant it to be long i, but the idea is the same.
I think this is not possible in D.
This seems possible:
auto i = v.getValue!int;
Indeed... it was just a thought, with that you could remove
certain requirements for overriding opCast, and might handle
implicit casting... actually that makes sense, allowing for a
limited number of types you want it to automatically change to
rather than using 'alias this' to subtype it.
It also doesn't seem like it would be difficult to add, only
'auto' would cause any real errors (as it's not a known type it
can return).
