Everything doesn't have to have an operator! We use operators a bit too much. It hurts readability of code when lines start looking like APL. On Fri, Dec 12, 2014 at 2:15 PM, Wojtek Narczyński wrote:

The lens package defines (&) and (<&>) as flipped ($) and (<$>), respectively. There is nothing in the base package that defines those. <&> is quite uncommon. Flipped ($) is something that crops up here and there. Sometimes called (|>), or (#).

A the bottom.

-- /Since: 4.8.0.0/ (&) :: a -> (a -> b) -> b x & f = f x

I learned about it from #haskell channel.

Everything doesn't have to have an operator! We use operators a bit too much. It hurts readability of code when lines start looking like APL. I agree. Furthermore I think '$' (and by extension '&') is dreadful. We should have gone with '<|' and '|>' like e.g. F#. It is a shame

It's not too late, these two operators are not taken. This has been discussed previously, but rejected for fear of namespace

There is (>>>) in Control.Arrow. It can be used for `flip ($)`.

No, sorry. I was confusing it with flipped function composition. 2014-12-18 17:48 GMT+01:00 Johan Holmquist :
