Description

I'd like to be able to specify a macro in the following manner: rule(foo: :bar).each where both foo and bar are arrays.

Examples

As an example please have a look at this spec that's currently failing: https://github.com/dry-rb/dry-validation/compare/master...DawidJanczak:macro-on-deeply-nested-rule

Contributor guide

Research direction
Examine the failing test spec and understand how macros are currently applied to rules, then identify where the deep nesting path is broken.
