Comment (by evhan):

 Transcribed from IRC: basically, {{{##sys#canonicalize-body}}} reorders
 internal definitions so that multi-valued assignments always follow
 normal ones. The result is always a bunch of let bindings to introduce
 the vars followed by a bunch of {{{##core#set!}}} nodes to assign them,
 but the normal and multi-valued var/val pairs are accumulated in
 separate lists so the ordering gets lost. Then, the templating just
 blindly puts the multi-valued {{{##core#sets!}}} after the others.
 Currently, the "dimensions" of the lists are different, so to speak --
 in the code, vars/vals gets a list of variables/expressions, whereas
 mvars/mvals gets a list of lists of variables/expressions -- and
 mvars/mvals has to be processed a bit more to produce a c-w-v.
