[ESM] Does not work with "type": "module" in "package.json"

[cedx]

I'm using the new ES modules features from Node.js 12 (the next LTS).

If I set my package to be an ESM one with the field type set to module in package.json file, the gulpfile.esm.js file stops working as expected.

import {spawn} from 'child_process';
       ^
SyntaxError: Unexpected token {

If I set the type field to commonjs, the gulpfile.esm.js file works as expected (but not my code which uses only ES modules).
It would be nice if interpret could manage this case (i.e. that the new ESM parser is already enabled).

It's likely not going to happen in interpret because then interpret would need to read package.json files. Maybe you want to open this on esm?

OK, done: standard-things/esm#789
