Hi Brent,

Re: '"if" expressions, not statements' is an elegant clarification, one definitely for the haskellwiki, if not there already.

Just for completeness' sake, bottom is a value for any expression. Wouldn't making the else clause optional by defaulting to "undefined" worthy of consideration for Evil Haskell?

Doesn't that already exist in 'case x of True -> ...'?
