## 1.0.2

**`(fix):`** Rename `Union#member?` to `Union#type_member?` to avoid rubocop-minitest's
`Minitest/AssertIncludes` cop incorrectly autocorrecting `assert obj.member?(x)`
to `assert_includes obj, x`. The autocorrected form calls `Module#include?` which
raises `TypeError: wrong argument type Class (expected Module)` on union type tests.
