Emacs don't start sending an erroneous error, backtrace at the end of 
this report.

Error points to the docstring of the function below, notably at the 
escaped ‘x’:

---
(defun lean-input-compose (f g)
  "\x -> concatMap F (G x)"
  (lexical-let ((f1 f) (g1 g))
    (lambda (x) (lean-input-concat-map f1 (funcall g1 x)))))
---
