It always > annoys me when languages use that symbol That's unlikely, as was discussed in this thread previously: a) JavaScript already uses "=>", and it doesn't make sense to be different just for the purpose of being different. That will only confuse people. b) Python already uses "->" for function return *type*. And there's idea to generalize it to *function type* in general. E.g. a function "(a, b) => a + b" can have type "(int, int) -> int". (I agree that intuitively, types would rather have "fatter" arrow, because types are "meta", but again, that doesn't correspond to the practical context we live in. So, let's look at the bright side of it - "=>" is more visible, because otherwise, arrow functions are really skinny and can be easily missed at all). > > On Sat, Feb 13, 2021, 14:52 Paul Sokolovsky <pmis...@gmail.com> wrote: > > > Hello, > > > > On Sat, 13 Feb 2021 09:24:51 -0800 > > Matthias Bussonnier <bussonniermatth...@gmail.com> wrote: > > > > > Works well with 0 parameters and currying, read almost like a > > > haskell function definition. > > > > > > f = () => ((b) => b) > > > g = (a) => (b) => b+a > > > h = (a) => (b) => (b, a) > > > i = (a,b) => a > > > > > > print(f()(2)) > > > print(g(1)(2)) > > > print(h(1)(2)) > > > print(i(1, 2)) > > > > Thanks for testing!
