This might be a somewhat controversial proposal: allow users to require from internal folder, like require('internal/fs.js').

One can already use the hidden modules in the /lib folder, like:

require('_http_agent');
require('_http_client');
// etc.

However, I am not aware of a way to access the modules in /lib/internal folder. Does anyone know a way to require those? Are there any issues with that?

I know that in this form it would conflict with the internal package, so the exact syntax has still to be figured out.

This could be provided as "use at your own risk".
