That seems like a much better state of affairs. So I can expect in
an ideal world to just keep a copy of the latest stable Vala version,
and the original pessimistic view applies to the non-ideal reality
of software with its myriad bugs? (It is hard to tell when meeting
a new language - python versions are a real issue, so vala could
have been in the same boat hence the question...)
