Comment(by simonmar):
Rather than a single new proposal, I think what would be most useful would
be a summary of the previous proposals and their pros and cons, so that we
don't have to rediscover all this.
e.g. we previously didn't like `\case` because we wanted a way to have
multiple arguments too: lambda currently allows multiple arguments, and
`\Just x ->` is a function of two arguments, whereas `\case Just x ->` is
a function of one argument. I'm not necessarily discounting the idea on
this basis, but it is arguably an inconsistency.
Another alternative is to introduce a new keyword for anonymous multi-
clause multi-argument functions, e.g. `fun`.
