[erlang-questions] Lists Comprehentions vs. Accumulators

[Shimon Cohen]

Hi

My question concerning section 3.12 in Joe's "Programming Erlang":

Why odd_and_evens should be less space efficient than odd_and_evens_acc ?

I guess it must be somthing with tail-recursion, but can't see why
List Comprehetions can't be implemented tail-recursive or even as a plain
loop.

Thanks,
Shimon Cohen.
