I used to think this as well, but have since changed my mind about most
cases.
The same for me.

All these factors combined just means that you have to concentrate
just as hard to understand one line of Haskell as you might 10 or 20
lines of other languages. There is 10 or 20 times the amount of
information.
This is right.
The problem is that often (IMHO) a function definition can be rewritten
so that it is much more readable.
As an example, with the takeList function I posted.
In other cases, you can just break long lines, introducing intermediate
functions that have a descriptive name *and* a type definition.
Doing this is an art, but a coding style for Haskell should try to
document this.
