Use a maybe monad :

This doesn't require a language construct. Also, if null check

pervasive in your code, you probably have a problem somewhere.
There seems to be an implementation here:
https://bitbucket.org/qznc/d-monad/src/5b9d41c611093db74485b017a72473447f8d5595/generic.d?at=master
It doesn't look as good as what you're suggesting,
auto rht = Applicative!Maybe.right(r1, r2);
auto ii42 = Maybe!(Maybe!int).just(i42);
Any idea how that maybe monad would cascade through into the
pointer accessors?
With opDispatch. That is how it is supposed to work.
