[Haskell-cafe] Arrays in Clean and Haskell

Let me see whether I understoodnd you correctly... If I read the contents of a file, the string will may be lazy (or something like that) and  not consume memory? In fewer words,  will the string behave like the infinite list of random numbers that I have used in the examples I posted?

  From this description, it's hard for me to see what is hard
  for you. When you "parse the file" I imagine you in face
  "parse a String" or "parse a lazy ByteString" (a much better
  idea). Take that `String` or `ByteString` and pass it to an
  `ST` computation that parses it to make an `ST` array and then
  operates on the array.
