Issue #8377 has been updated by headius (Charles Nutter).


More cases of ambiguity:

obj::FOO is always a constant lookup. obj::FOO() is always a method call.

obj::foo is always a method call. There's no way to omit parens for a :: call if the method name is capitalized.

I support removal as well. It doesn't add anything and it confuses more often than not.

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.
