Since DTF does not implement `equals()`, even if we implement `equals()` for the `ClassicFormat`, we would basically still need to implement our own `equals()` for a DTF to effectively compare the ClassicFormats.

The comment "does not implement equals and thus cannot be represented as a pattern" doesn't explain why it can be represented as a pattern. Can that be explained better?
