Hi,

Range-based for declares a range and two iterator variables as auto&& and
auto, respectively. This is unexpected if you declare your loop variable
static or thread_local. This also means that a stackless coroutine cannot
yield from and return to the middle of the loop - which would be the basic
use case for generators.
I'd suggest to have the range and the two iterator variables have identical
storage class specifier as the loop variable (i.e., range declaration).
This would allow one to switch() / goto into the body of the loop.

Thanks,
-lorro
