I think it's abuse (putting the let on the first line makes it difficult to
see), but I see no reason why it should be forbidden, except in style
guidelines. Indeed, there may even be situations where it's the preferred
idiom...
I do have a question, though:
Is "\\" implemented so that it would be possible to do this?
let
! \\ var1 $ bar x
! ! var2 $ quux x
! nitz var1 var2
If not, I still think it would be a good idea to extend the implementation
to be able to do this; it makes the block a little more compact, and a
little more readable. I'd also expect that it wouldn't be too difficult to
implement.
