in thread while(<>) { ... } considered harmful

I disagree with saying that map is considered harmful. As I noted in other reply in this thread its behaviour is consistent with other Perl operators: for/foreach and grep. In my opinion it is while(<>)'s magic is wrong. It should localize $_ so it doesn't affect outer scope.
