The key factor is that a dependency should be a "callable".

A "**callable**" in Python is anything that Python can "call" like a function.

So, if you have an object `something` (that might _not_ be a function) and you can "call" it (execute it) like:

```Python
something()
```

or

```Python
something(some_argument, some_keyword_argument="foo")
```

      assertThat(command).isInstanceOf(WrappedRunnable.class);
      inline.execute(command);
    }

    private static <T> void assertTaskWrapped(Collection<? extends Callable<T>> tasks) {
      Predicate<Object> p = Predicates.instanceOf(WrappedCallable.class);
      assertTrue(Iterables.all(tasks, p));
    }
  }
