常见的想当然

Calling to_set on an existing Set produces a new Set instance for safe mutation, and calling to_set on a Set subclass preserves the receiver subclass.

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#to_set with default arguments returns self instead of a new duplicate set, so mutating the result modifies the original set in-place
• assert calling to_set on a Set subclass with default klass downcasts the receiver to a base Set instead of retaining the subclass
• assert calling to_set with an explicit klass argument constructs an instance of the specified class
• assert calling Set#to_set with a block returns a newly allocated Set rather than returning self
• assert Enumerable#to_set with default klass converts any Enumerable into a base Set instance
