This should definitely be supported out-of-the-box, we can take a closer look in Discord or through GH Issues! But generally I would expect:

```

[[modules]]

path = "foo"

depends_on = []

[[modules]]

path = "bar"

depends_on = ["foo"]

```

would do the trick, assuming both are within a configured source root, and their children are _not_ also marked as modules. If the children are marked as modules, their dependency rules are treated separately and wouldn't automatically inherit from a parent.
