Well, here's a sample session I recorded just now:

C:\>\ghc\ghc-6.2.1\bin\ghci
   ___         ___ _
  / _ \ /\  /\/ __(_)
 / /_\// /_/ / /  | |      GHC Interactive, version 6.2.1, for Haskell 98.
/ /_\\/ __  / /___| |      http://www.haskell.org/ghc/
\____/\/ /_/\____/|_|      Type :? for help.

Loading package base ... linking ... done.
Prelude> let p = 1 : [2 * x | x <- p, x < 1] in p
