But if you see

    foo( out( a ), b, in_out( c ) )

you can be fairly sure that a and c might change, and be somewhat sure that
a doesn't have to be initalized, c has to, and b won't change (since the
above demonstrates that the implementer put some thought in it). That can
still be useful information.

Unless I'm missing something.
