Try thinking of it this way: it's only a bareword if
it would make use strict whinge at you. Thus, the
constructs you cited are all non-uses of barewords,
such as in use Foo or require Foo or Foo => 1, or
even $x{Foo}. And I have proposed (nonRFC) that
Foo->bar() also be not a bareword. Yes, I know
strict doesn't carp about it, but that could be Foo().
