Can you point me at your code and these tests please?

I was also thinking of this solution when the bug this commit fixed was
originally reported.  The question is whether the information needed to
extract these traits is available and correct at the time of the dump.
Hopefully whatever is causing the strange missing-declaration behavior
will not break this solution too.

I'll add this to my to-do list but I'm about to go on vacation so I
won't get to it for a couple weeks.
