make-sequence doesn't understand derived types

[davidmullen]

For example:

(deftype buffer32 (&optional (size '*))
  `(simple-array (unsigned-byte 32) (,size)))

Then:

> (make-sequence 'buffer32 1024)


Debugger called in: #<thread "Initial" active (3405) 0x7f49db5ee740 7f49d8ba3000>.

#<a SIMPLE-ERROR 139955071156416>:
    Cannot find the element type in vector type BUFFER32

I will rewrite cl:make-sequence in the coming days. It is just too ridiculous as it stands right now. Let's keep this issue open until the rewrite is done.
