In Common Lisp, there are no non-key rest-args when you have keyword
parameters. After the required and optional arguments, there must
follow an even number of additional arguments, and every two of them
are treated as a keyword/value pair.
I think it makes sense the way CL specifies this. Anything beyond
this would lead to confusion. If you want to go beyond what (ice-9
optargs) offers, yo are probably best off writing your own argument
parser.
