Subject: Rescue clause or equivalent for catch?

Does having a rescue clause for catch sound like a good idea to anyone?

You could write this:

    catch (:error) {

	# Do stuff

	do_stuff()		# throws :error
	do_more_stuff()		# throws :error
	finish_stuff()		# throws :error

    rescue

	# Oops, stuff failed, clean it

	cleanup_stuff()

    end
    do_junk_whether_stuff_failed_or_not()

instead of this

    catch(:done) { 
	catch (:error) { 

	    # Do stuff

	    do_stuff()		# throws :error
	    do_more_stuff()	# throws :error
	    finish_stuff()      # throws :error
	    throw :done
	}
	# Oops, error, clean up
	cleanup_stuff()
    }
    do_junk_whether_stuff_failed_or_not()

Just wondering.
