Literals are ugly. Let's remove them.

True/false:

2.0.0p0 :001 > !Date
=> false
2.0.0p0 :002 > require Date.to_s.downcase
=> true

Integers and floats:

A search for 'using' on http://www.ruby-doc.org/core-2.0/index.html returns, well, nothing. So, what is it?

2.0.0p0 :001 > method(:using)
=> #<Method: main.using> 
2.0.0p0 :002 > _.source_location
=> nil

So it's some kind of method on main with no source location. Hmm. Well, the changelog mentions ri ruby:syntax. Let's try that.

Documentation

We have also made documentation improvements which many rubyists have requested. We have added a huge amount of rdoc for modules and methods. 2.0.0 will be around 75% documented while 1.9.3 was about 60%. Also, we have added a description of Ruby's syntax. You can see:
