[Bug] Using ${foo.bar} returns ${foo} if foo is not a container

[odelalleau]

cfg = OmegaConf.create(dict(foo=0, bug="${foo.bar}"))
print(cfg.bug)

The above code prints "0" while I would expect it to crash.

What puzzles me is that this behavior is actually tested right now:

def test_indirect_interpolation2() -> None:
    d = {
        "a": {"aa": 10},
        "b": "${a.aa}",
        "c": "${b.aa}",
    }

    cfg = OmegaConf.create(d)
    assert cfg.c == 10

This test doesn't make sense to me: accessing cfg.c should crash since b is equal to 10 so b.aa should be invalid. Am I missing something?

This looks like a bug in the test and in the code.
This makes more sense:

def test_indirect_interpolation2() -> None:
    d = {
        "a": {"aa": 10},
        "b": "${a.aa}",
        "c": "${b}",
    }
