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...
