Hello

I'm getting the following error on latest master if I run for eg. describe-symbol:

condition-case: Symbol’s function definition is void: internal-make-closure

toggle-debug-on-error results in:

Debugger entered--Lisp error: (void-function internal-make-closure)
  (internal-make-closure (x) (v-or-f) nil (funcall (nth 1 x) (internal-get-closed-var 0)))
  (cl-some (internal-make-closure (x) (v-or-f) nil (funcall (nth 1 x) (internal-get-closed-var 0))) describe-symbol-backends)
  (if v-or-f (cl-some (internal-make-closure (x) (v-or-f) nil (funcall (nth 1 x) (internal-get-closed-var 0))) describe-symbol-backends))

  call-interactively(describe-symbol nil nil)

I bisected it to the following commit:

ce48658191 Fix command repetition with lexical-binding (Bug#29334)

I don't have the deep understanding required to properly fix this so I
just reverted ce48658191 and my problems went away :)

Can someone more knowledgeable please attempt a proper fix?

Thank you
