I never said it was a _good_ approach ;)

While I'm _definitely_ not going to advocate for this approach as a 
valid solution, I have to disagree with this being an issue.  While it's 
more lines in the given example, if there were dozens of such 
assignment-within-conditional calls in the same code, the additional 
LOCs become negligible.

This is true. But conversely, just because I think something is a bad 
idea doesn't mean someone else can't have found a valid use for it.
