Requirements may be added, updated, and removed with 'go get'.
The vendor directory may be updated with 'go mod vendor'.
A typical sequence might be:

    cd src  # or src/cmd
    go get golang.org/x/net@master
    go mod tidy
    go mod vendor

Use caution when passing '-u' to 'go get'. The '-u' flag updates
modules providing all transitively imported packages, not only

As the `get_current_active_user` dependency has as a sub-dependency on `get_current_user`, the scope `"me"` declared at `get_current_active_user` will be included in the list of required scopes in the `security_scopes.scopes` passed to `get_current_user`.

The *path operation* itself also declares a scope, `"items"`, so this will also be in the list of `security_scopes.scopes` passed to `get_current_user`.

```Python
# This won't work, because get_burgers was defined with: async def
burgers = get_burgers(2)
```

So, if you are using a library that tells you that you can call it with `await`, you need to create the *path operation functions* that uses it with `async def`, like in:

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```
