This proposal loosens closure requirements to support developer flexibility. It removes the _ in requirement that bypasses explicit argument use and allow closures to use any, all, or none of the implicit $n variables as needed or desired.

Method cascades offer a method-based counterpart to functional chaining. In functional chaining, partial results pass from one step to the next. In cascades, object scope is maintained through a series of sequential calls. Both approaches support fluent interfaces, providing readable streamlined code.
