Pissed off about functional programming

To me, the argument to convince oneself that Haskell's = "assigmnent" is not the same beast as C's and Python's is the following: the binding it defines is also valid in code before it.

I think I didn't get this :( Care to explain?

    main=print n
    n=42

In C or Python, this would print 0 or undef or some random contents. In Haskell, it prints 42. The "assignment" reaches back to instructions before itself. Which ought to hint it's not really an assignment in the (my) usual sense of the word.

In Haskell, I can:

    x = 0:y
    y = 1:x
    main = print $ take 10 y

Producing output:

    [1,0,1,0,1,0,1,0,1,0]
