Hum... At least not in Haskell.

Starting with the mostly dependent code makes a large difference in readability. It's much better to open your file and see what are the overall functions. The alternative is browsing to find it, even when it's on the bottom. Since you read functions from the top to the bottom, locating the bottom of the function isn't much of a help to read it.

1 - The dependency order does not imply on any ordering in abstraction. Both can change in opposite directions just as well as on the same.
