design ponderings: plist to alist

[Thien-Thi Nguyen]

This fragment (from gnugo.el):

bin0ou6tUH3QO.bin
Description: application/emacs-lisp

includes a function to convert plist (succinct to humans) to alist
(succinct to computers).  I spent 20 minutes poking around the Emacs
source searching for something builtin, to no avail.  I saw a few cases
of the opposite direction (alist to plist) and many cases where plists
are walked at time of use (e.g., the C code for text-properties), so
maybe this is a hint that plist to alist (pre-use) is a net lose.  :-/

What do people think?
