[gentoo-user] ephemeral keyword override?

[Ian Zimmerman]

When I'm thinking about installing a package, I can say

USE='foo' emerge -p some-cat/some-package

to see what would happen, without changing any /etc files.  Is there a
similar way to specify a keyword override, without changing
/etc/portage/package.accept_keywords?  Something along the lines of

ACCEPT_KEYWORDS='<=some-cat/some-package-9999 ~amd64' \
USE='foo' emerge -p some-cat/some-package

or am I dreaming?
