The "falls out" is the issue with me, as I see the {} as being "contained
within",
the "}" was never crossed, so to me it was still the same {} block. I could not
find this "reinitialize" issue in my old K&R book?

I don't see while(true){} being any different than for(;;){}
in this context, and while(true){} causes the Lint error
of "evaluation of constant value boolean".
