However, I picked up the broader context obsession too and in case we’de dealing with legacy code I would:
– make logger an optional parameter that defaults to the real implementation.
– in tests, pass in the Fake logger
– in production, not touch the calling code
just because I won’t have access to all the places where a RomanSequence is created.
In some languages this add a compile-time dependency from RomanSequence to RealLogger, but it’s slightly better than a dependency to STDERR.
