Greeting Alchemists,
in order to implement schema diffing, it would be nice if two similar
ColumnDefault objects would be comparable as such. I attach a path to
implement such test. Would it make sense to add this support in
Alchemy's core or should a schema diffing library add it through
monkey patching?
