I attach a revised version of the patch, that fixes the typo, improves the parser by allowing parentheses in version range expressions, and adds a check that the new syntax is accepted only by cabal >= 1.8.
Argh! That patch still contains a very obvious bug. Here is yet another revised version.
Applied. The scope for problems in this bit of the code seems quite high. I fixed two more issues. :-) The check on using the new syntax was not quite right. The problem is how we represent >= in terms of UnionVersionRanges (EarlierVersion v) (ThisVersion v). For example this dep violated the check: ">= 1 && < 2" I also fixed the pretty printer to respect operator precedence. Duncan
