No, what I pasted was straight from one of the Boost examples. Boost is considered the C++ gold standard.
The solution to writing unmaintainable code and ensure a job for life is simply to use C++ ;)
Boost likes extending the language to see where it can go. :)
In that case, we have operator() returning an inserter object that accepts operator(), which returns itself (or another inserter object).
The += trick is new -- how did they do that?

You probably should return a Vec& from the *= operator to keep it consistent with the base types' counterparts.

boost::assign creates an overload for operator += with a vector on the left hand side that returns an object that has the comma operator overloaded. You can look at the actual header for the details.
