 During a macirb session:

          ± irb
         irb(main):001:0> class NSURL
         irb(main):002:1>   alias_method :to_s, :absoluteString
         irb(main):003:0> end
         => NSURL
         irb(main):004:0> NSURL.URLWithString( 'macruby.org' )
         RuntimeError: can't modify frozen/immutable string

         irb(main):005:0> test = NSURL.URLWithString( 'macruby.org' )
         RuntimeError: can't modify frozen/immutable string

         irb(main):006:0> test.to_s
         => "macruby.org"
         irb(main):007:0>

 macirb seems to be trying to do something to strings it get's from calling
 #to_s
