Page 226, definitions of co and contravariant
Prior usage is murky, (Meyer uses the terms in the context of data fields, Khoshafian and Abnous combine argument type and return type). However, the most critical reading of prior use would seem to indicate that I have the two definitions backwards.

Situations were, should be situations where (fa)

BTW A machine crash some time back deleted a file that held several other reported errata that I had not yet verified. If you are looking for an errata you reported previously and do not see it, please let me know once again.
