Emotional Ruby

I had no idea that numbers in Ruby were so emotional:

$ irb
ruby-1.9.2-p290 :001 > 5.public_methods.sort
=> [:!, :!=, :!~, :%, :&, :*, :**, :+, :+@, :-, :-@, :/, :<, :<<, :<=, 
:<=>, :==, :===, :=~, :>, :>=, :>>, :[], :^, :__id__, :__send__, :abs, 
. . .
:untrusted?, :upto, :zero?, :|, :~] 
ruby-1.9.2-p290 :002 >
