Well, simply extending the Haskell syntax to allow

it. Guarded
right-hand-sides could be allowed too.
Introducing layout after \ will break a lot of programs. For example, consider the way >>= is often formatted:
f >>= \x -> g >>= \y -> ...
I guess that's why Marcin suggested using a new keyword.
Ah yes, I forgot that lambda expressions are often used like that (actually, I think that this use of the syntax is horrible, but that's just MHO). Cheers, Simon
