... which is a rather large hammer - a much larger hole in the type system
than friend would create.  Still, if you put the class that needs a friend
into an assembly by itself, and put the class that will be it's friend into
an assembly by itself, you get nearly the effect of friend, but who'd want

Practially speaking, you're better off putting the friends in the same
assembly and using internal and just live with the fact that all the other
classes in that assembly have more access than they need.
