D does not have `friend` declarations. Equivalent functionality is
achieved by `private` being module-private rather than
aggregate-private, meaning that all you have to do is to put `abc` in
the same module as `def`, and it will have access to all `def`s private
members.

If, however, you're trying to inject friend access to something outside
def's module, then you might want to reconsider what you're trying to
accomplish and whether it can be done differently.
