Phil Steitz commented on MATH-431:
----------------------------------
I would say go ahead and commit the latest patch to trunk and we can continue
to work on validation tests. We can discuss whether we want to adopt the
various corrections that R makes. The key is to document clearly how our code
works. We will also want to properly externalize the exception messages and
select the right exceptions from the 3.0 hierarchy.
