ppx_import - javascript-style imports for reason/ocaml

Why?

This is more concise than doing a ton of lets, and more specific than an open.

What does it look like?

Now you get to

[%%import thing][@@from Source1];
[%%import (Sub1, Sub2)][@@from Source2];
[%%import (one, Two.Three ((), four, Five.Six))][@@from Source3];

which turns into

let thing = Source1.thing;
module Sub1 = Source2.Sub1;
module Sub2 = Source2.Sub2;
let one = Source3.one;
module Three = Source3.Two.Three;
let four = Source3.Two.Three.four;
module Six = Source3.Two.Three.Five.Six;
