We're all assuming here that HaXml deliberately decided to change the interface. Is that really true? (only Malcolm can answer)
Yes, I had a glance at it and AFAICT he changed the name of the submodule Text.XML.HaXml.Xml2Haskell to something more suitable.
Most of the time I guess that the interface will change by accident, without people spotting. Perhaps we are trying to solve the wrong problem...
You have a point, interface change by accident is a different problem. But it doesn't make the other one wrong. Clearly not all interface change is by accident; see above. But without a way for the author to declare it, we're effectively treating all these instances as change by accident as well, which means more maintenance. -Sven
