Subject: String#to_rx ?

Possible RCR: would anyone else find this a useful addition to the core

class String
  def to_rx
    Regexp.new( Regexp.escape(self) )
  end
end

as a more straightforward & readable alternative to interpolation:

/#{Regexp.escape(a_string)}/

I turned up a few references to this sort of thing in ruby code on the web.
