Lo que suele suponerse

Passing a block to Set.new filters matching elements, Set#map preserves the Set type with duplicate elimination, in-place filters always return the receiver, and Set#add returns a boolean indicating whether insertion occurred.

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

Contrato

• assert Set.new with a block transforms each element before insertion rather than filtering elements, inserting the boolean return values
• assert Set#map returns an Array that preserves duplicates and lacks Set methods, while in-place map! mutates the receiver into a Set
• assert Set#select! and Set#reject! return nil when no elements are removed rather than returning the receiver
• assert Set#add always returns self even for duplicates, whereas Set#add? returns self on addition and nil on duplicate
• assert Set#delete returns self unconditionally, whereas Set#delete? returns nil when the element is absent
• assert Set#flatten only unpacks nested Set instances, leaving nested Array instances intact
• assert Set#=== tests element inclusion for pattern matching, while Set equality with Array is always false
