Certainly being actively worked on - mostly/entirely by Richard Smith
(cc'd) & I think he's prioritizing some of the nastier edge cases as they
come up in the standardization process, so "practical" bugs (once where the
desired behavior is clear enough & it isn't likely to significantly impact
the design/implementation in a significant way) might be a bit lower
priority.

Generally welcome, I should think! :)

Fair - though they're pretty related - not sure it's worth having a
separate bucket. But not a big deal either way.

Thanks for filing! :) (what does GCC do, I wonder? Not sure if the support
over there is near enough to support things)
