in thread Is this DBM::Deep behavior, or something with tie/bless?

A few thoughts:

• Those isX() methods belong in Scalar::Util (or something similar). I have similar snippets in DBM::Deep itself for the exact same reason.
• You need to localize $SIG{__DIE__} within those evals. In doing this for DBM::Deep, I found Test::More does things with die handlers that get tripped up with this.

Rather, $SIG{__DIE__} handlers need to detect that eval is in effect ($^S -- even though it still isn't perfect). $SIG{__DIE__} is (by far) the 'worse' magic and so needs to take the burden for "playing nice". "Simple" use of eval doesn't need to be made even more complicated. local( $@ ); is another safety measure that is missing from the simple examples. Quite the mess.
