Add implicit partially applied operator function syntax

(< 5) => (lambda x: x < 5)
(5 +) => (lambda x: 5 + x)

I like very much the (-> ? + 2) suggestion 😃 (more consistent than $ imo)

But why is ( < 2) , your first suggestion, eliminated ? That’s very elegant, the shortest (and what I’m used to with livescript’s functional library). Chaining transformations like that is a joy, there’s nothing redundant, what’s in there matters:

[ { id: 1, title: ""}... ]
|> filter(.id > 3)  
|> sort-by(.title)  

instead of

[ {...}]
|> filter( -> ?.id > 3) # or ?['id']
|> sort-by( -> ?.title)

which is pretty good also 😃

@vindarel Thanks for the input! I think I’m currently leaning towards 1, and that will probably be what gets implemented in the next release.
