+;;; Commentary:
+;;;
+;;; This is a convenience module for porting Goblins to Hoot while Guile support
+;;; is incomplete. It simply re-exports some extant Hoot prompt functionality
+;;; and adds call-with-escape-continuation and call/ec.
+;;;
+;;; Code:
+
+(define-module (ice-9 control)
+  #:use-module (hoot control)
+  #:export (make-prompt-tag
+            default-prompt-tag
+            call-with-prompt
+            abort-to-prompt
+
+            %
+            default-prompt-handler
+
+            call-with-escape-continuation
+            call/ec))
+
+(define (call-with-escape-continuation proc)
+  "Call PROC with an escape continuation."
+  (let ((tag (list 'call/ec)))
+    (call-with-prompt tag
+      (lambda ()
+        (proc (lambda args
+                (apply abort-to-prompt tag args))))
+      (lambda (_ . args)
+        (apply values args)))))
