Overview
A base class for classes which must identify a coercer to be used. If the strict
argument is true, it won’t coerce the given value but check its type. More information there dry-rb.org/gems/dry-types/1.2/built-in-types/

.collection_coercer_for(type) ⇒ Object
Returns a collection coercer which corresponds to a given type. Example:
collection_coercer_for(Array)
