Issue #17004 has been updated by Eregon (Benoit Daloze). Agreed as well on the point of "if I observe it with `p/puts/IRB` I don't want the method call to behave differently. Debug printing should avoid having side effects, and this makes a significant way to break that. Sounds also very confusing when benchmarking some method and leaving an unused variable vs removing it and seeing a large difference/maybe the benchmark doesn't do at all what it intended. ---------------------------------------- Feature #17004: Provide a way for methods to omit their return value https://bugs.ruby-lang.org/issues/17004#change-86411 * Author: shyouhei (Shyouhei Urabe) * Status: Open * Priority: Normal ---------------------------------------- In ruby, it often is the case for a method's return value to not be used by its caller. 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>
