If you want to restrict opCast, then use a template constraint,
constraining
it to what you want to work with it. Also, casting away const
is generally a
bad idea in D. Casting away const and mutating a variable is an
_extremely_
bad idea. You _really_ shouldn't be doing it. So, the fact that
you _have_ a
function which is specifically trying to cast away const is
almost certainly
_not_ a good idea.

So, you mean that if i declared any parameter as const, it have
to stay const all the time?
What would you do, if you need in a special case a mutable
version or must change the object itself?
Because there is no "mutable" keyword in D you have to cast away
the constness.
