Iavor and I just made the trivial modification for DoAndIfThenElse
Any comments on this modification? How do people feel about the suggestion that we do it for case statements as well?
I'm happy to allow the change for if-then-else. The need for extra indentation there has annoyed me a few times. However, I have never come across the case-of expression variation in practice. Indeed, the wiki page is not very clear on what exactly the problem is. For instance, until a few minutes ago, the given example was merely: case whatever of blah -> bluh blah' -> bluh' However, that is already perfectly legal Haskell'98. I just changed the example to read do case whatever of blah -> bluh blah' -> bluh' since that is what I thought was perhaps intended. And indeed that is rejected by a H'98 parser. But it seems a bit of an unlikely coding style. And it now occurs to me that perhaps something different was intended. The following is legal H'98: case whatever of Cons -> bluh Nil -> foo But stick it in a do block and it ceases to be accepted: do case whatever of Cons -> bluh Nil -> foo Now for myself, I tend to strictly indent the alternatives in a case expression, but I can see that if you prefer non-indented alternatives, then the latter would indeed be annoying.
