If you mean something like



then you can use

    has_version 'cat/foo[coolfeature]' || ...

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.
