This removes the concept of equality between operations to guarantee compatilibity with Python 3. Python 3 requires equality to result in identical object hashes. It's impossible to implement a unique hash that preserves equality as operations such as field creation depend on being able to accept arbitrary dicts that cannot be hashed reliably. Thanks Klaas van Schelven for the original patch in 13d613f80011852404198dfafd1f09c0c0ea42e6.
