I've recommended before that the default should have been something
like your USE HOST, NONE. I would prefer the syntax to be a little
different.

   IMPORT : only-list ! imports only those things named (or renamed) on the
list

or (current default)

   IMPORT ALL

or (my preferred default)

  IMPORT NONE

Note that my only objection to your syntax is that it requires HOST to
be a reserved name that can't be used as a MODULE name.
