pipeline vs composition

foo.hs

-- pipelining
let x = 1
    doubled = x * 2
    squared = doubled * doubled
    decremented = squared - 1
  in decremented
  
-- composition

let x = 1
    double = (*) 2
    square x = x * x
    decrement x = x - 1
  in (decrement . square . double) x

@raganwald, Thanks for responding!

I'm not sure I understand the distinction. In this case, both let statements could just be the body of a first-class function, which could be named, passed around, composed, etc.

Maybe this example is just too small.
