deconstructable 0.1.0

This gem provides Deconstructable, a mixin module that helps you to support pattern-matching over your types. Usage -------- ``` class Thing include Deconstructable ... deconstructable :x, :y deconstructable def foo do_the_foo end end ``` This class provides a single DSL method `deconstructable` which helps you to mark methods and attributes as deconstructable. Deconstructable attributes will be made available in pattern matching, e.g.: ``` thing in Thing(foo:, x: 100, y:) ``` Classes that include `Deconstructable` gain an implementation of `deconstruct_keys` that permits hash-style key based pattern matching. Positional array-style patterns are not supported.
