Composable - Included

#&

#|

Alias for 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?,
#with_matchers_cloned

Historically, a single matcher instance was only checked against a single value.
