A skeptical, meaningless gem
I can't conceive of a single reason to include this in your application. Let's
say you want to try it out, though. Run bin/console, then at the prompt,
initialize Nilist.
[1] pry(main)> Nilist.new
=> #<Nilist:0x007fca0a0a5588#<Nilist:0x0>Most method calls will return nil, while predicate methods will raise
UnprovableError.
Bug reports and pull requests are welcome on GitHub.
After checking out the repo, run bin/setup to install dependencies. Then, run
rake spec to run the tests. You can also run bin/console for an interactive
prompt that will allow you to experiment.
