Even when a method returns something meaningful, its caller is free to ignore it. 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 be optimized, by for instance skipping creation of complex return values. The 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: <mailto:[email protected]?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
