You're missing a back-compat borkage for an undocumented feature.. calling 
list methods on hashes used to fall through, now it doesnt, it just doesnt 
call them.. (It always returned one obj instead of an array if there was 
only one, but you didn't notice because it tried list methods after 
hash methods couldnt be found..

See my recent emails.
