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)?

Feature #8377: Deprecate :: for method calls in 2.1

=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.
