I've idly wondered before whether we should add a general mechanism for
this to avoid having to create functions that look at
`command-line-args-left' themselves.  (And --eval is problematic in
circumstances like this.)

So something like

--function foo --function-args bar zot gazonk

would result in calling `foo' with those arguments.

Hm...  would we need some way to say "here's the end of
--function-args", perhaps?  "--"?  So:

--function foo --function-args bar zot gazonk --

Anybody have any thoughts here?
