We also have the typecast operator to automatically convert WeakConstPointerTo's to the required kind of actual pointer.
This introduces ambiguities which the compiler will resolve one way or the other, but we don't care which way it goes because either will be correct.

Returns an ordinary pointer instead of a WeakConstPointerTo.
Useful to work around compiler problems, particularly for implicit upcasts.
