Edebug throws an error if you try to instrument a use of map-let. To
reproduce, enter the following code into *scratch* (using emacs -Q if
you like):

(require 'map)
(defun map-bug (tag map)
  (map-let ((tag a)
	    ('spam b)
	    bar)
      map
    (message "%s %s %s" a b bar)))

(map-bug 'foo '((foo . 0)
		(bar . 1)
		(spam . 2)))

Evaluating this code normally produces the message "0 2 1" as expected.
But position the cursor inside the definition of map-bug and use C-u C-M-x
and you will receive the error Invalid read syntax: "Expected lambda
expression".

I tried replacing map-let's debug spec with this, and it is working for me:

(debug ((&rest &or symbolp ([form symbolp])) form body))
