This is not right: fn alone is a keyword parsed by the parser as a
"delete function" command. When you type

; fn

to rc, you are saying "please delete these functions: (no arguments)". Now,
you are free to delete the above definition with

; fn fn

or even to define a new function

; fn foo { echo hi }
; foo
hi
;

I don't see how it's "impossible to define a new function". Is your rc
behaving that way? If so, it's broken and needs to be fixed..

This works on my machine. Could you please send me a more detailed bug
report? I'll try to fix anything that's wrong...

I must apologize, maybe I was a bit hasty!

Rc prompts how I told it to, but I'm sure it didn't by the time I wrote my mail
because I double checked it. Maybe this is due to doing all my experiments in
the same shell.
Anyway, my difficulties with setting the prompt aren't reproducible when
using a new instance of rc.

As I understand Byrons answer, there is no way to redefine fn (any builtin?)

I was just playing around with rc (1.1gamma) and discovered this (strange?)
behaviour:

1) If I define a function fn like "fn fn { printenv | grep '^fn_' }"
   the output is always nothing and it is impossible to define a new
   function, because fn now has a different meaning. Bug or feature?

2) Why doesn't this work:
   fn prompt {	if(~ ($status) 1 2 3){
		prompt=('err ' '>> ')
	} else	prompt=('ok ' '>> ')}
   I want the prompt to show "err " if the last command returned 1,2 or 3,
   else "ok ".
