Nit: You're also welcome to =default this in the header if the bots like it

Linking error for `= default` in the header  :(

[Peter Kasting, 2017/03/31 06:09:59]

Oh?  I would have expected the warning, if any, to be a presubmit complaint
about not having complicated inline functions.

Sorry for the confusion. First I just commented out from .cc file. so that
presubmit didn't blame.
After removing, presubmit complaint about not having complicated inline
functions.
