Write Scheme code for interpreter in JavaScript to create a with-handler macro

[login to view URL] describes the with-open-file and unwind-protect macros in Common Lisp. [login to view URL] describes the problems of creating a macro similar to unwind-protect in Scheme. Using the nearly R5RS-compatible Scheme implementation at [login to view URL], I would like to have macro that would allow me to write code something like this: (with-click-handlers 'block-1' 'block-2' (define mouse-input-1 (get-mouse-input 'block-1')) (define mouse-input-2 (get-mouse-input 'block-2')))
