3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function.

    So, it is a generator function that transfers the "generating" work to something else internally.

<h4>ASM 4.1</h4>
<p>The plug-in includes software developed by the ObjectWeb consortium as part
of the ASM project at <a href="http://asm.ow2.org/">http://asm.ow2.org/</a>.</p>

<p>A subset of ASM is re-packaged within the source and binary of the plug-in (org.eclipse.sisu.space.asm.*)

We are still using the same `OAuth2PasswordRequestForm`. It includes a property `scopes` with a `list` of `str`, with each scope it received in the request.

And we return the scopes as part of the JWT token.

!!! danger
    For simplicity, here we are just adding the scopes received directly to the token.

```Python
some_var.set("new value")
```

To get a value anywhere inside of the context (e.g. in any part handling the current request) use:

```Python
some_var.get()
```
