@jaror I never liked it; I think if you can't be bothered to assign a name, point-free combinators are what you should be using.
I also think it gets much uglier or complicated (or both) once you have arguments (unlike getLine, but like most subroutines).
That said, I wouldn't take it away from anyone. I think the desugaring is unsurprising and, at least in a strict language, semantics preserving.
I haven't really spent the necessary time to think clearly through the non-strict case.
@JRepin For most purposes, I think tmux is the better software.
