If you do that, what benefit is ValueUnpackingError over just
ValueError?
unpacking (a generator) still doesn't wrap ValueError, and ValueError
is raised a lot more than ValueUnpackingError.
Has anyone actually had that problem? And if they did, make it:
result = tuple(Foo.save())
try:
x, y = result
except ValueError:
...
You could even check the length of result before assigning it if you
wanted to do something fancier without exceptions at all. But it seems
silly to me.
Since I've seen no actual examples of code that would benefit, I'm still
-1 on this particular exception, and -1 on a general-purpose addition of
exceptions.
