// So... I started making some refactorings to the implementations of DataSource.
34
// It turns out all of the implementations of ok() would only return true. Since they
35
// all did the same thing, I lifted the implementation into the base class. Now, since
36
// it is always true, we can eliminate it. I think that it is better to always check the
37
// return values of the read*() functions, anyway, as ok()'s meaning is unclear (can we
38
// read in the future? did a read fail in the past?)
39
//
40
// When this ok() call is removed, make sure to check that any nearby read*() calls are
41
// actually testing the return value.
