It's not exactly hierarchical, but Groom most certainly should help
with getting much prettier output:

Hi all,
The derived Show instance is useful, but I sometimes wish for something that's easier to read for big data types. Does anyone have an implementation of show that draws things in a hierarchical manner? Example:
Given
data Tree a = Leaf | Bin Int a (Tree a) (Tree a)
and
value = Bin 1 (Bin 2 Leaf Leaf) (Bin 3 Leaf Leaf)
draw as
Bin 1 Bin 2 Leaf Leaf Bin 3 Leaf Leaf
Cheers, Johan
