Greetings.

My question is not directly related to Haskell.

Is it possible to encode an array using lamda terms only, and recover =
the term specified by an index term in O(1) time (in other words in one =
step reduction, without cheating using several steps behind the scenes)? =
Or is it possible in any rewriting system? I might not be making any =
sense, but I am sure there are people out there who can read my mind, =
and possibly put my question into better terminology.

Thanks
