If you want to micro-optimize this a bit, use `name.compare(kTypeNames[type]) ==
0`, which will avoid constructing a new string for each type.

Done.

It might be a bit better to return a success value from this function and put
the type into an outparam, so we can distinguish between unknown types and the
default type.

[Daniel Nishi, 2014/07/10 19:00:07]

Good point. I was thinking about maybe placing a NOTREACHED() there on the way
to work this morning, but this solution sounds better.

Done.
