If you mean something like


then you can use

instead.

built_with_use cat/foo coolfeature || ewarn "bar will be more useful if you rebuild cat/foo with USE=coolfeature"

What does this report if cat/foo does not have coolfeature use flag in
some version? Meaning can this support cases which need --missing true.

False. If for instance coolfeature was made optional in >=pv you can use logic
like:

if has_version '>=cat/foo-pv' && ! has_version 'cat/foo[coolfeature]'; then
   ewarn '...'
fi

Unless someone objects with good reasoning of course.

I think this should cover all the current functionality with built_with_use. So when before EAPI 2 goes live I will commit: 23:29 < zmedico> has EAPI 0 1 || die "build_with_use is only allowed in EAPI 0 or 1"
