I would be all for this if we could get something like 
opImplCast() which would basically be the same as opCast() but 
without requiring cast.

I believe the operator overloads must be static for it to work 
properly with ex. `Foo foo = 100;`.

```
Foo foo = 100; // Would trigger static void opImplCast(T)(T 
value) where T is int.
int a = foo; // Would trigger ex. static T opImplCast(T)(Foo 
instance) where T is int
```

You should of course be able to be explicit about types like `int 
opImplCast(Foo instance);`
