Subject: [ruby-core:44204] [ruby-trunk - Feature #6270][Rejected] add "??a" support for "not defined?(a) or a.nil?"


Issue #6270 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Rejected

As Eric pointed out, it's conflicting existing syntax.  I don't reject the basic idea (though I am excited), so try again with new syntax if you really want this.

Feature #6270: add "??a" support for "not defined?(a) or a.nil?"

It would work like this:

    ??foo #=> nil

    foo = nil

    ??foo #=> nil

    foo = 3

    ??foo #=> true

Not sure if this would be useful, just a suggestion.
