You have mentioned needing an allMembers that excluded functions in one
of your other posts. The following thread was exactly about that. I can
never remember the solution, but I found it again: :)

(Although JSON is not mentioned in there, that thread has been inspired
by marshalling as well. :))

std.exception.enforce is the right choice in that case. You don't want
the checks to disappear when asserts are turned off.

That makes sense too. There is enforceEx() to throw a specific type of
exception.
