O que costuma-se supor

Set#<=> provides a total ordering across any sets so arrays of sets can be sorted with Array#sort.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• Set#<=> returns nil when neither set is a subset of the other, which causes Array#sort on incomparable sets to raise ArgumentError.
• Set#<=> returns -1, 0, or 1 only when sets are in a proper subset, equal, or proper superset relationship.
• Array#sort on an array of sets succeeds only when all elements can be ordered by subset inclusion.
