Hmm - but there is something wrong, I get

Debugger entered--Lisp error: (void-variable --cl-block-x--)
  (throw --cl-block-x-- 'dynamic)
  (return-from-x)
  (catch --cl-block-x-- (return-from-x) (throw --cl-block-x-- 'lexical))
  (let ((--cl-block-x-- (cons '--cl-block-x-- nil))) (catch --cl-block-x-- (return-from-x) (throw --cl-block-x-- 'lexical)))
  (x-block)

for the originally posted example.
