rollup lazy top scope for node deps thoughts

blah.js

let nodeDeps = {};
let nodeCache = {};

// some dependency
Object.defineProperty(nodeDeps, 'some_module', {
  get: () => {
    if (process.argv[2] !== 'hello') throw new Error('hello must be first argument');
    const nodeModule = nodeCache.some_module || { world: () => console.log('world') };
    return nodeModule;
  }
});

// e.g. src/main.js

nodeDeps.some_module.world();
