# Description & User-Facing Changes

This PR allows enables the following uses, which are all no-op.
```nushell
source null
source-env null
use null
overlay use null
```

The motivation for this change is conditional sourcing of files. For
example, with this change `login.nu` may be deprecated and replaced with
the following code in `config.nu`
```nushell
const login_module = if $nu.is-login { "login.nu" } else { null }
source $login_module
```

# Tests + Formatting
I'm hoping for CI to pass 😄
