Subject: Re: substring: to the end of the string

class String

  def substring       

     /(^...)(.*)\z/ =~ self

     return $2

  end

end

"123456".substring 
  = >"456"


Now......

I am just wondering how can I build dinamically the Regexp
I mean ...

"123456".substring(5)
 = > "6"

"123456".substring(4)
= > "56"

ideas ?

-r.
