Instance Method Details

#make_enumerable! ⇒ Object

This overrides String#each with StringRay#enumerate, thus allowing us to include Enumerable. Be careful, this breaks lots of existing code which depends on the old methodology of String#each! The overridden String#each functionality will be exposed as String#each_at.
