常见的想当然

Calling the spaceship operator <=> or relational comparison operators (<, <=, >, >=) on Sets performs a total ordering comparison based on size or element values so arrays of sets can be sorted, and comparison methods accept any Enumerable.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• assert Set#<=> returns nil when neither set is a subset of the other rather than ordering by size or elements, causing Array#sort across disjoint sets to raise ArgumentError
• assert Set#<=> returns -1, 0, or 1 only when sets have a subset, equality, or superset relationship
• assert relational operators <, <=, >, >= on disjoint sets evaluate to false in both directions rather than establishing an ordering
• assert subset and relational comparison methods raise ArgumentError with 'value must be a set' when passed an Array, while set algebra methods (+, -, &, |, ^) accept any Enumerable
• assert Set#<=> returns nil when comparing a Set with an Array
