This kind os parameter is known to be confusing since you cannot tell just looking at the method call what the parameter mean. For example: ```ruby object.respond_to?(:symbol, false) # what does `false` mean? object.methods(true) # what does `true` mean? ``` Now compare that to ```ruby object.respond_to?(:symbol, include_all: false) # what does `false` mean? object.methods(regular: true) # or object.methods(only_public: true) # or object.methods(include_all: false) ``` I know Matz doesn't like a breaking changes, so maybe we could have both to not break current calls, but allow a nicer syntax in newer Ruby? I don't know the depths of the Ruby C implementation, so here's what I thought in plain Ruby: ```ruby def respond_to?(symbol, include_all_positional=false, include_all: nil) include_all ||= false # ... end ``` I'm willing to tackle this, if approved. -- https://bugs.ruby-lang.org/ Unsubscribe:
