O que costuma-se supor

Mustermann.new always allocates a new pattern instance and pattern.params simply delegates to pattern.match to retrieve cached parameter hashes.

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

Contrato

• Mustermann.new returns the identical cached pattern instance for matching strings and options via WeakMap memoization rather than allocating a new pattern object each time.
• Mustermann.new with different options creates and caches a distinct pattern instance.
• pattern.match caches Mustermann::Match objects so consecutive calls with the same path return the identical memoized Match instance and cached params hash.
• pattern.params bypasses Match allocation and match caching, returning a newly allocated Hash directly from regexp named captures.
• Mustermann.new with cache: false disables Match caching, returning a new Mustermann::Match instance on each match call.
• Mustermann.new with a custom cache hash routes cached Match objects into the caller-provided hash table.
• Composite pattern operators retain memoization so unioning identical patterns returns the same composite instance.
