To be clear, .env/ini are both kv formats & likely* could use the same internals. What's unergonomic about defining kv options as kvs in config? With JSON I'm forced to write a bunch of extra syntax & still nest NODE_OPTIONS(?) IMO feels like we're putting config in an extra place for no reason

Some things that will (fairly soon) Just Work in Cloudflare Workers:
import { readFileSync } from 'node:fs';
readFileSync('/bundle/config');
const r = await navigator.storage.getDirectory();
const tmp = await r.getDirectoryHandle('tmp');
const file = await tmp.getFileHandle('foo',{create:true});
import { readFileSync } from 'node:fs';
readFileSync('/bundle/config');
const r = await navigator.storage.getDirectory();
const tmp = await r.getDirectoryHandle('tmp');
const file = await tmp.getFileHandle('foo',{create:true});

copilot (claude sonnet 4) spent 15 mins writing failing unit tests and modifying irrelevant existing code. i threw it all to trash, writing the tests from scratch myself now. junior devs may not know everything, but they at least know what they don't know. and that makes a whole lot of difference.

Coming soon in @Cloudflare Workers, we will be enabling use of eval only at the top level scope. This means that you'll soon be able to use eval and new Function(str) during the start up of your worker. It'll still be disabled within requests. Hat tip to @yagiznizipli.com who landed the PR today.
