Oh, the issue is because Goblins exports a procedure named `$`, so the `$` in the `match` expression is no longer treated as a syntax literal.

Here’s a working program:

```scheme
(use-modules (hoot records)
             (ice-9 match)
             ((goblins) #:hide ($)))

(define-record-type <foo>
  (make-foo bar)
  foo?
  (bar foo-bar))

(match (list (make-foo 1) (make-foo 2))
  ((($ <foo> bar)
    ($ <foo> bar*))
   (pk (cons bar bar*))))

```

This gets rid of the `$` operator entirely. To get it back, you can rename it with an import expression like `((goblins) #:select ($) #:prefix g:)`
