Issue #8377 has been updated by matz (Yukihiro Matsumoto). * we haven't reached consensus to remove double colons for method calls from the language. * even if we do, 2.2 is not the right time to remove, maybe 3.0. * we have convention of Array class and Array(obj) conversion method, why not Foo::Bar and Foo::Bar(obj)? Matz. ---------------------------------------- Feature #8377: Deprecate :: for method calls in 2.1 https://bugs.ruby-lang.org/issues/8377#change-39221 Author: charliesome (Charlie Somerville) Status: Open Priority: Normal Assignee: Category: Target version: current: 2.1.0 =begin (({::})) is usually a constant lookup operator, but it can also be used to call methods. This can confusing to people learning Ruby. I propose deprecating (({::})) as a method call operator in Ruby 2.1, then removing it in 2.2 (or whichever version comes after 2.1). As part of the deprecation, Ruby's parser should emit a warning whenever (({::})) is used as a method call operator. This warning should be emitted even if (({-w})) is not enabled. =end -- http://bugs.ruby-lang.org/
