I'm not sure how easy it would be to spot all state
declarations in LVALUE
contexts. Might be quite easy. Curiously, subroutine entry
seems to work
just fine:

$ ./perl -Ilib -wlE 'sub outer {sub up {$_[0]++}; for (1..3)
{up(state $a); print $a;}} outer(); outer();'
1
2
3
4
5
6

Not sure why that's not the same class of operation.
