I found a problem with it, when I tried to use the array in a string context the backend segfaulted with: "WARNING:  Deep recursion on subroutine "main::encode_array_literal" at -e line 74" just before the segfault. I think the problem is in the regexp check in 'encode_array_literal' (it's obviously reversed comparing with the original one),

Yeah, I noticed that after I sent it out :(.

I seem to recall fixing this post email as well... Can you provide the
function that broke so I can double check? (Or was it part of the
regression test?)

Thanks for taking the time to play with it.
