Does literate programming in haskell (.lhs) support the idea in Knuth's WEB of using aliases for blocks of code? In other words doing something like<br><br>main = do<br> <part 1><br> <part 2><br><br><part 1> === putStrLn "foo"<br>
<part 2> === putStrLn "bar"<br><br>(except I don't know what the actual syntax is)</blockquote><div><br></div><div>No, and it's not as necessary in Haskell as it was in Pascal because it's easier (and preferred) to break programs up into smaller functions anyway. So your <part 1> is just part1, and the definition of part1 follows later. (Consider that we don't throw around state in variables quite as wontonly; and when we *do* need to, we can stuff it in a state monad.)</div>
