From @ysth

with code like​:

while (my ($k,$v) = each %ENV) { local %ENV; $r = keys %ENV; print "$k=$v\n" }

the keys in the loop resets the iterator for the original %ENV hash,
resulting in the each always returning the first key,value pair.

From The RT System itself

This is more than likely a misunderstanding
between the use of local() and my().
