  Irb takes the latter as the beginning of a regular expression for the
first argument of to_f:

>> (DateTime.now - Date.new(2006,9,15)).to_f /30
/
ArgumentError: wrong number of arguments (1 for 0)
        from (irb):10:in `to_f'
        from (irb):10
        from /usr/lib/ruby/1.8/rational.rb:520

  Cheers,
