When I got somebody else's C-Code, I used gnu indent to bring it into a layout I liked (and could easily grasp). One of the points I like about Haskell is just its use of space: it makes things clearer and doesn't clutter up your screen as it does in C. I definitely had less problems with layout in Haskell than with forgetting braces in C (and line them up nicely).
unambiguous one using spaces) . I think it's really the fault of ASCII for allowing the tab character code which has user-defined semantics, just like the other abomination the form-feed character.
That's because of its history: ASCII was used first for telegraphs, so TAB was just a shorter way of saying "make some space", same with form-feed, the bell, and all those other characters from 0-31 you never use. If somebody wants to write his/her Haskell code with braces, so be it - unless you develop in a group, then you should have layout rules anyway. Perhaps somebody could come up with a "Haskell indent" (part of a pretty printer?)? Markus
