Well... a couple of things here.
It's definitely preferred to use initializers like above. Whether that
code is in .h or .cc is sort of up to judgment.
The nice thing about putting some (especially smaller) pieces of code in
the headers is that it can be inlined elsewhere. So while I agree with
you in theory from a code cleanliness perspective, from a practical
perspective we wind up with a pretty decent amount of code in the headers.
