suggestion: undo removal of guards from lambdas, especially (but not only) if pattern guards make it into the language.

thanks. I'm a fan of the correspondence principle, and as we have a LetCase, there should be a LambdaCase as well (the other seems to be inspired by Lisp's cond?). but the syntax is slightly awkward. is there a reason not to merge LambdaCase and Lambda, thus addressing both my suggestion and the LambdaCase proposal? f <pat> | <patguard> = <rhs> \ <pat> | <patguard> -> <rhs> case x of <arms> (\ <arms> ) x claus ps. strawpoll-2 has both LambdaCase and MultiWayIf as 'no'. but that is numbers, not rationale..
