nit: import

[Yoyo Zhou, 2014/12/18 02:38:33]

This is also only ever #included, not #imported.

[tapted, 2014/12/18 03:30:55]

scoped_nsobject.h is objective C-only (it won't compile in .cc). style guide
says it should be import, so I always import. I guess include wins a grep-fight
though 396 vs 94.`git grep -h 'scoped_nsobject\.h' | sort | uniq -c`. /shrug

[Yoyo Zhou, 2014/12/18 22:42:07]

Yeah, I miscounted and there are some #imports. As long as it's #imported
somewhere else, I don't feel too out of line. =)

nit: a short comment? (just to satisfy the objc style guide...)

[Yoyo Zhou, 2014/12/18 02:38:34]

Done.
