Mostly what that tells me is that the network stack is full of code
that I want to stay far, far away from.

A good compiler should be able to see a copy to an intermediate
structure and a subsequent use of that structure and elide the copy
entirely, accomplishing the type-punning in the implementation rather
than in the expression. This seems like a good goal to work towards.
