Oh, you expect cl-progv to bind lexically?  I interpret the first
sentence in its docstring to mean that cl-progv does dynamic binding,
not lexical binding.  Note also, that if it did bind lexically, we would
not be able to compile the body form.

(defmacro cl-progv (symbols values &rest body)
  "Bind SYMBOLS to VALUES dynamically in BODY.
