Of course in real life maintenance coding, your journey will not be finished with a nice .startsWith("foo"), instead you encounter .startsWith(FOO) and can still count yourself lucky if you find FOO defined as "bar" (because $reasons) in a way that does not allow principle of maximum surprise redefinitions somewhere else. All for getting a somewhat reliable understanding of what the trivial entry point line does when trying to understand code downstream in the control flow.
