Wow, that's nicely hidden. Thanks for digging that out! I would like to
nominate this for the obscure feature of the week award.
@Eli:
I can see that implemented in cl--do-arglist, which calls itself
recursively for such lists like in our case used as function parameters.
cl--do-arglist is used (indirectly) by cl-flet, cl-labels, cl-defun,
maybe others.
cl-defun's doc string even contains has hint
"...The full form of a Common Lisp function argument list is
...
VAR may be replaced recursively with an argument list for
destructuring,,,"
I don't think cl-flet/cl-labels have that.
@Michael:
Not remembering much about Edebug, but cl-defun seems to work with
Edebug. So... :-)
