Jason,what do you think about deprecating the ARM-era for-scope handling that allows:
void f () { for (int i = 0;;); i = 2; }
we noisily accept that in c++98 mode with -fpermissive. It wasn't even well formed then. Implementing this has some unique requirements in the name-lookup machinery, which I ran into again today.
Option A: rip out now because it's a c++98 ARM-compatibility crutch Option B: deprecate in gcc-8 and remove in gcc-9. nathan -- Nathan Sidwell
