no, you're not binding :b:, you nee to tell MATCH wheere/how to bind it, like


{ window;
  isolate (:a:) /buggaboo/
  isolate (:b:)
  match [:a:] (:: :b:) /()boo/
  alter (:b:) /FARRR/
  output /:*:a:\n/
}

which rightly yields

buggaFARRRboo

note 'boo' is still there, since we matched the null string at its left.
