Yeah. I happened not to write it that way here, but if I'd been reviewing
someone else's code and they'd done it that way, I'd not have objected.
In the case at hand, I'd personally avoid a ternary op for the first
assignment because then the line would run over 80 characters, and
you'd have to make decisions about where to break it. (We don't have
a standardized convention about that, and none of the alternatives
look very good to my eye.) Then it seemed to make sense to also
write the second step as an "if" not a ternary op.
