USING does the same thing += does: it makes it harder to make a mistake.
I guess you *could* think of `+=` as a way to avoid repeating yourself
syntactically, but in many languages, there's actually a semantic
difference (the left-hand term is not re-evaluated for augmented
assignment). Moreover, in the cases where there is no semantic
difference, then you can switch between the two forms freely. Neither
one is "more applicable" than the other.

There's no "could" about it.  += helps one avoid misspellings, especially when field names are similar.

Seriously, John.  I think sometimes you argue just to argue. It's ... offputting.
