I wonder that people use this pattern! (I'd never used it except test). ---------------------------------------- Feature #15955: UnboundMethod#apply https://bugs.ruby-lang.org/issues/15955#change-80265 * Author: nelhage (Nelson Elhage) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- I'd love a way to apply an UnboundMethod to a receiver and list of args without having to first `bind` it. I've ended up using `UnboundMethod`s in some hot paths in my application due to our metaprogramming idioms, and the allocation from `.bind` is comparatively expensive. I'd love `unbound_method.apply(obj, args���)` to be equivalent to `unbound_method.bind(obj).call(args���)` but without allocating the intermediate `Method` -- https://bugs.ruby-lang.org/ Unsubscribe:
