The only thing I still don't understand yet: Do we support things like that?

I.e. should we add things like

> if has test ${FEATURES} && ! use test ; then
>         eerror "FEATURES=test requires USE=test."
>         die "FEATURES=test set but not USE=test"

if a package's src_test phase requires some conditional stuff or is it
something like "user shoot himself into the foot" so we do *not* care
because we still assume "if FEATURES=test, USE=test is *normally* set"?

Asking from user experience point of view: Imagine a user tries to
emerge a package which will compile multiple hours and src_test just
fails because some conditional stuff didn't run due to USE=-test
accidentally set by the user (in the past or was forgotten).

The code above in an early phase like pkg_setup would prevent such a bad
user experience, not?
