Is 78 characters still a good option? Was: [Haskell-cafe] breaking too long lines

Of course they are. My point was not that everything should be clear  
without parenthesis, but that the user shouldn't have false  
impressions - the notation should either give a true impression (like  
Daniel suggested, with every other line indented more than the  
previous one - though I don't like it), or not to give any impression  
at all, so that the reader would be forced to read the noise.

Well, then, is that ALWAYS so obvious that this particular name  
denotes a transformer? Of course, if it's not a standard transformer  
like StateT or WriterT, but something written by the same guy who  
invented this MyCoolMonad type?
