[Pdx-pm] defined $var->{key} changes $var in to a hashref?

[benh]

ok I guess I should rephrase, I understand ~why~ it's doing this
($var->{} builds out the hash, not defined), but it's not quite what
my ~expectation~ was. What I was thinking was going to happen was more
along the lines of:

grep{$x = $_; $x->{key}} $var

so that $var was not touched... though I can't think of a good way for
defined to effectively clone in place as the transformation would have
already happened as far as defined was concerned.
