| bool can_choose_non_starable | ( | SELECTOR(T) | ) | const |
Whether it is possible to call choose_non_starable.
There's no need for can_choose_starable, since Zero is always starable and therefore can be chosen.

Specialization of contains that always returns false.
Indeed, elements structured by a particular type are always incompatible with structural elements of another type.
