Re: [Haskell-cafe] Confused about Cyclic struture

Another question, it's said in the book that using cyclic structure (like ones = 1:ones) , the list would be represented by a fixed amount of memory.

Does it mean [1,1,1......] only occupy one cell of memory ? How about in " take 100 [1,1,...] " ?

'take' will certainly ignore the cyclic structure. Even if it could detect the cycle in its argument there is no way to represent the list of 100 elements more efficiently.
