| Subject: | Dump() affects success of subsequent each() |
Thank you for the module. I use it often.
It seems that YAML::Syck::Dump($hashref) doesn't reset the iterator for
%$hashref when it's done. A subsequent each(%$hashref) fails to iterate
at all. Placing keys(%$hashref) before the each() call resets the
hash's iterator and allows each() to iterate normally.
I've attached a Test::More test case illustrating the problem.
I've flagged the Severity as "Important". No offense will be taken if
you flag it as less severe.
