I imagine that there are probably some pre-processors that would return a
WARNING for it.
Modern Visual Studio and GCC both flag the "=" in a condition, I believe. But
if you're shipping code with 260+ warnings, who would see one more.
There's a pretty good chance the heat pump you're using right now has those
warnings. Alas...
