I wrote that last paragraph after I had written the other stuff and
then tested ksh.

Damn. That doesn't work, because the printing functions just output
`foo "$@"' for the not-really-existing call. Hm. What are we supposed
to do here? Handle positional parameters differently? Output a special 
comment as for the other function flags (but that doesn't work with
$functions, but the eprog flag is lost there anyway) or... use another
special option for autoload (but that wouldn't work for $functions
either because that flag-losing thing).

With `work for $functions' I mean: eval "foo() { $functions[foo] }" or 
some such.

Bye
