Loads ES modules and WebAssembly with CJS interop in Node, roughly according to https://github.com/nodejs/node-eps/blob/master/002-es6-modules.md.

WASM support is currently only provided for Node 8 nightly.

Follows the NodeJS resolution algorithm, loading modules first as CJS and then falling back to ES on import or export syntax failures. This effectively provides the "export {}" assumption to load an ES module.

This does mean a double-parse, over the mjs approach currently being taken by Node.

Built with the ES Module Loader polyfill 1.0 branch at https://github.com/ModuleLoader/es-module-loader.

Execute an ES module file:

For example, where module.js contains:

Note that only the default import form for CommonJS modules is supported.

Also supports dynamic loading via the dynamic import syntax:

Source maps for errors are fully supported through the source-map-support project.

Source maps also work in Node 6 with the node --inspect flag via:

• Does not currently support the "module" package.json proposal described in the second paragraph at https://github.com/nodejs/node-eps/blob/master/002-es6-modules.md#51-determining-if-source-is-an-es-module
• Does not allow any loading of ES modules from within CommonJS itself
• Does not implement global require filtering described in https://github.com/nodejs/node-eps/blob/master/002-es6-modules.md#521-removal-of-non-local-dependencies
• Does not provide CJS exports as named exports, skipping the algorithm defined in https://github.com/nodejs/node-eps/blob/master/002-es6-modules.md#311-dynamicmodulecreateo this may change, pending Node implementation intentions

Alternative Babel options can be set with a local .babelrc file.
