Well, the prompt part is your prompt function getting imported from the
environment & interpreted by the rc parser. Since this happens only
once (and a good thing!) you only see it once. The "wrong name" is just
a convenient trick used to munge the environment string into something
the parser will recognize.
I suppose it is debatable whether rc -n should be interpreting fn
prompt at all---I hadn't thought of this up to now and offhand I
should say the answer is no. I will fix this.
Lists are parsed "backwards" because of yacc. Doing it the other way
would consume yacc stack space proportional to the length of the list.
Anyone up for writing a recursive-descent parser for rc? (just
kidding...)

This is wierd:
; rc -x -n
fn x {switch($status){case [^'~'^0]*;echo '# status' $status;}}
; ls
ls
It prints my prompt function, but only once, and without the correct
name.
One other wierdness... lists print as, e.g.,
path=((($minpath $miscpath) $nfspath) .)
That seems backwards to me. Wouldn't
path=($minpath ($miscpath ($nfspath .)))
be more aestetic?
