Comment(by jeltsch):
Replying to [comment:63 simonmar]:
> Another alternative is to introduce a new keyword for anonymous multi-
clause multi-argument functions, e.g. `fun`.
Note that when introducing a new construct for functions, we should
introduce an analog construct for arrows. If we introduced a new keyword
`fun` for functions, we would have to introduce another new keyword for
arrows. If we would reuse `\` as in `\ case`, we could reuse `proc` in the
same way (`proc case`). This is not to say that I particularly like the
proposal with `\ case`, but that the syntactic construct that we come up
with should reuse `\`.
