#values_match?

This provides a generic way to fuzzy-match an expected value against an actual value.
#|

Alias for Matchers::Composable#or.
#should_enumerate?

We should enumerate arrays as long as they are not recursive.
#surface_descriptions_in

Transforms the given data structure (typically a hash or array) into a new data structure that, when #inspect is called on it, will provide descriptions of any contained matchers rather than the normal #inspect output.
#unreadable_io?,
