There is no use-case for this request and it would cause many incompatibilities (e.g. in rake, thor, ruby itself, ...):

https://github.com/jimweirich/rake/blob/bfafc3a0/lib/rake/application.rb#L300
https://github.com/ruby/ruby/blob/8612344834d4/lib/test/unit.rb#L398
https://github.com/ruby/ruby/blob/8612344834d4/lib/test/unit.rb#L398

The only "problem" is that some of you dislike the fact that a method ending in '?' returns something else than `true` or `false`. This is similar to `String < Hash` returning `nil`. Embrace Ruby, love it for its clever quirks. Or else I'd suggest writing your own new language instead of trying to "reinvent" Ruby.

I'll let Matz reject this request. In the meantime, I'm accepting wagers from anyone that thinks there's a chance that this will ever be accepted.

Numeric#zero? returns true or false, while Numeric#nonzero? returns self or nil.

I've written a patch that fixes this inconsistency and adds a Numeric#nonzero (non-predicate) method that returns self or nil for chaining comparisons. I'd like for this to be included in Ruby 2.1.0.
