Minor: I'd have included a comment on this method to say that if immediate
then the return value will be `Maybe<Object>` whereas if `!immediate` then the
return value of the callable will be the actual `Object`. The difference of
those semantics are not obvious in the method, but are relied upon by the
caller.
It's surprising that the same method is used to return the two different
styles of result, but I see why you did it (to reduce duplication).
