Message-ID: <9305270453.AA05584@netapp.netapp.com> (raw)
There are no heirarchical lists in rc. Therefore you can't embed the
null list in an argument list to anything.
~ takes just two lists as arguments. Maybe this will make things clearer:
~ foo (foo bar) (FOO BAR)
reduces to
~ (foo) (foo bar FOO BAR)
and evaluates to true. The arguments to ~ don't enjoy any special
property that you might imagine. They are just a word list.
