Hmm. I think the provided example captures most of what i care about,
float area(float radius) { return 3.14159 * radius * radius; }
and even forgotten/disguised uses of, say, M_PI, would fall in that
category after-all.

If i'm not mistaken (i've never put it to real use)
-Wunsuffixed-float-constants would handle that. So, it wouldn't be as
airtight as -Wdouble-promotion but still good enough and a fantastic
improvement.
