Even when a method returns something meaningful, callers are free to ignore them. Why not provide a way for a method to know if its return value is needed or not. That adds a room for methods to optimize, by for instance skipping creation of complex return values. Following pull request implements `RubyVM.return_value_is_used?` method which does that: https://github.com/ruby/ruby/pull/3271 -- https://bugs.ruby-lang.org/ Unsubscribe:
