Subject: 27.0.90; Can't edebug cl-defuns with &aux destructuring
Date: Sat, 04 Apr 2020 18:17:52 +0200

Insert into *scratch*:

(cl-defun foo (&aux ((a . b) '(1 . 2)))
  (list a b))

Now try to edebug this function (move point into it, hit C-u C-M-x).
This gives an error:

Debugger entered--Lisp error: (invalid-read-syntax "Expected one of" arg nil)
  signal(invalid-read-syntax ("Expected one of" arg nil))

Did you load cl-macs before running edebug?

No, but it also doesn't seem to make a difference.

My guess is that in the specification

["&aux" &rest &or (symbolp &optional def-form) symbolp]

we should replace 'symbolp' with 'cl-macro-arg'. This might cause
other issues, however, as that specification is probably no longer
decidable.

Actually, &optional uses the same thing, which appears to work fine,
so I went ahead and implemented this with commit
73be4d1ed5b190bd93e9bad6aebe43d0dea0d7d3.
