[Haskell-cafe] Which tab width do you prefer for Haskell code?

Hi everyone, I'm trying to get a feel for the modern Haskell community's opinion on default tab-width for HIndent. Here is a link to the online poll: http://doodle.com/poll/82xf854t9mmuv22h#table Quote:

For the HIndent tool we'd like to choose the standard tab width. For now, it is 4, the width set by the Johan Tibell style guide. A survey of 1000 top-downloaded packages on Hackage reveals about 50-50 either way:https://gist.github.com/chrisdone/e3d1796d8f5df717b91db54aae36c440 HIndent is meant as a "community standard" tool; it should reflect the community's actual practice. If there's a clear preference for 2, we'll switch to that. Otherwise, we remain with 4.

Cheers!
