`position' in rep...?

[Christopher Roy Bratusek <nano tuxfamily org>]

Hi all,

just a small question, whether I'm blind, or whether rep really doesn't 
ship a function like `position'.

so `nth' gives the the value of the nth element:

(setq mylist '("Crux" "StyleTab" "get-S-tabbed"))
(nth 1 mylist)

=> StyleTab

but now for the opposite? other lisps do ship `position':

(position "Crux" mylist)

=> 0

Now it seems to me that REP does not ship a position function? Atleast I 
couldn't find one in the docs neither via `git grep'. I think that's 
essential, so I'm sure it's somewhere. Or... did John expect everyone to 
loop through lists?
