The above could be rewritten to:

ECONF_USE_WITH="'x X' 'foo libfoo' 'bar' 'python pygtk'"
econf $(use_with ${ECONF_USE_WITH})

or an eclass could even export this:

src_configure() {
	[ -n ${ECONF_USE_WITH} ] && USE_WITH="$(use_with
\"${ECONF_USE_WITH}\")"
	econf ${USE_WITH}
}

Guessing from what I see in the gnome/kde eclasses I think people will
implement the above then in eclasses and I therefore don't see why we
can't do it like that from the beginning...
(Besides, there are already shortcuts in eclasses like G2CONF="...")
