Description of Proposed Feature

It should be possible for AMD modules to access their URI as with requireJS (see doc).

The implementation would be quite simple:
https://github.com/systemjs/systemjs/blob/main/src/extras/amd.js#L43

    return [amdDefineDeps, function (_export, _context) {
        // expose the url 
       module.uri = _context.meta.url;

      _export({ default: exports, __useDefault: true });
      return {....}

In the client code:

define(['module'], (module) => {
    console.log(module.uri)
})

In what way would you use it?

The idea is to also allow AMD modules to resolve their path and load their own assets.
This was at some point briefly mentioned in #1939.
