.selectBy() is strictly oriented towards equality test. It's easy to
pass a dictionary to .selectBy().
When you need non-equality test one or more keys in your dictionary are
special. But there is no way to mark these special keys in syntax like
**dict. You know what keys are special but there is no way to express such
knowledge with a dictionary. Hence you need to use another, non-dict-based
approach.

This is the preferred way.
