Agreed, as far as that goes.  But `dolist' is an exception
(it is the only one, though).  There are _relatively_ few
such name clashes.

Yes, I think it does.  I wasn't aware of this feature.

From (elisp) `Dynamic Loading' it appears that there is
no bug here.  If you think so too then please close.

Why don't more (even most) of the files distributed with
Emacs have this variable set (to non-nil)?  Searching the
Emacs 25.1 distributed Lisp files, I find only these that
use the variable:

dired-aux.el
dired-x.el
wdired.el
wid-edit.el
calendar.el
cl-extra.el
cl-lib.el
cl-macs.el
cl-seq.el
sendmail.el
executable.el
pcvs-util.el

Why (only) those?
