It's an excellent guideline, but it doesn't always work in practice.

For example, we're designing arrays at the moment, and there's a real tension
between making them behave as much as possible like sequences, and making them
behave like we would want sequences to behave if we were starting from
scratch.

Design is always a matter of finding the best compromises between conflicting
goals.
