PPX usage

[cometkim]

It will be very nice if we support some syntax sugar using PPX

// let binding style
let%vec v = [1, 2, 3]
// extension
let v = %vec([1, 2, 3])

// thought it might be `vector{ 1, 2, 3 }` in the future, hope so

// turn into this:
let v = Vector.fromArray([1, 2, 3])

This will need native stuff and esy configuration. But I can support :)

since the syntactic sugar was disappeared, let%vec v = ... seems not possible as far as I know. But the using extension would be feasible.

let v = %vec([1,2,3])

I think I can contribute to it. Do you want me to make a PR for this feature?

Yes please!
