Yeah, this is what I'm proposing as well ... I feel Pierre's pain
with not wanting to rewrite and maintain deprecated code, but I
fear WO becoming what everyone hates about Tapestry, which is that
it goes through huge breaking revisions every release. There is a
large base of legacy apps, and especially if there are relatively
straightforward deprecation routes, it would be better to not break
than to break, I think (this is obviously subject to a religious
debate, I suspect). I'm especially wary of breaking changes that
just break semantics rather than syntax. In this case, it's
breaking the interpretation of random strings inside of WODs, which
will make for a really annoying fix. Alternatively, I suppose
someone could write a conversion app to convert all the old style
into new style, but that only partially addresses the issue.
Most of the symbols have a SDF equivalent, as seen below. And the
ones that don't wouldn't be difficult to provide functionality for by
subclassing SDT I would think (which still excludes api compatibility
with NSTimestampFormatter's other methods).
I'd be happy to whip this up later in the week and contribute to
Wonder if people want it.
