I think the non-applicable to code observation is very likely true –
we'd like to be able to write nice descriptive variable names. In
doing this, we probably want them to be more than the 1 or 2
characters that Haskellers traditionally use, maybe of the order of
Given this, it would seem a shame to only be able to fit 6-13
litterals on a line, that sounds like we'll quickly be having to wrap
lines with deffinititions of any significance on them.
My personal preference with Haskell is to ignore the 78 character
"limit", but only when layout otherwise becomes horrible otherwise.
Haskell is a very horizontal language, and to limit our horizontal
space seems pretty weird.
