[Haskell-cafe] Optimal line length for haskell

I wonder if people who like one giant window maybe don't use the REPL?
I keep 3 windows open: one with the editor, one with ghci, and one
with a shell. The shell I use for compiles, darcs records, diffs,
grepping, moving files around, etc. I don't understand how people are
able work with fewer... it's awkward to constantly ^Z out of the
editor, not to mention that you can't look at a diff, test output,
compiler output, etc. and code at the same time. With the REPL I'm
constantly jumping back and forth to fix type errors, test functions,
Since I have 3 terminals that basically means a strict 80 columns on
all but the widest monitors, but it's never a problem. Just define
more small functions. Breaking them up keeps the nesting down, gives
names to to sections, gives me something to test from the REPL, and
ensures there are regularly spaced toplevel type signatures, so a type
error doesn't propagate too far through inference.
I've tried with >3 terminals but I can never figure out what to do
with the extra ones. Now that I think of it, it would be interesting
to slave two vims together so the secondary one is always the %
buffer. Then I don't worry about who is opened where but can still
swap between current and last used quickly.
