Parenless function calling

[gabejohnson]

I like big butts, but not on my function calls

const sum3 = x => y => z => x+y+z;
sum3(1)(2)(3); // 6

Wouldn't it be nice to live in this world?

sum3 1 2 3; // 6

ASI is the big problem with this syntax.

sum3 1
     2
     3;

But maybe this could work

(sum3 1
      2
      3);

or this

sum3 1
   \ 2
   \ 3;

sum3 1 \
     2 \
     3;

I might prototype it in sweet.js to see where it goes.

Got schooled by the Founder. Maybe the \ could work.

\ is the string escape character and escapes line breaks if encountered by itself. Don't know if that would pose a problem in this case.

Although it would be in line with

var str = "multiple \
line \
string \
literal";

str // "multiple line string literal"

Python uses \ for line continuation as well.

(sum3 1
     2
     3);

Surely a Lisp that compiles to JS and happens to have builtin currying already exists out there somewhere, right?

(Now I'm going to wonder if anyone has ever invented a Lisp with Haskell's type system. Haskell in Lisp's clothing.)

@ScottFreeCode the parens were just for ASI suppression. But that won't work. \ might do the trick though. It should be a separate proposal.

Hmmm...there must be something 😄

I hope ASI will be removed completely one day.
