Adds support for Perl's Yada Yada Operator to Ruby 1.9.

gem install yada_yada

Whenever you've put a placeholder for a function in your source file, but it doesn't work yet, you can replace the body of the function by … (unicode U+2026 ELLIPSIS) and it will raise a NotImplementedError for you.

pry> def a; …; end
pry> a
NotImplementedError in a

If you are boring, and can't type unicode, then this is also aliased as yada_yada.

pry> def a; yada_yada; end
pry> a
NotImplementedError in a
