20 lines is a lot, but I have smaller ones all the time. You need >4
spaces of indent to continue a let. Here's another way to understand
why:
f = do
let x = some big
expression
y = another big
expression
x y
If you wonder why "multiple let" syntax is needed, well I don't really
know for sure, but consider if x and y were mutually recursive.
I was annoyed at first with all the indentation but got used to it. I
use 4 space indents so it works out ok. Binding with <- or in where
can reduce the indentation but is not always appropriate.
