Very nice obfuscation. I definitely couldn't read anything from it when I looked at the source.

Here's a way to make it resistant against Deparse. (It still doesn't print the canonical comma, I'm lazy to do that.)

$;="+[^,}",$/=($;^'[>,@]')."-".(('^|*!]@~/*%*..*]]./[@;.^,^\,{@\?@;,"}
+@`|')[$;]^';^]@/.^^[~`[]^}<@@/(^\~|;.@[(=\+^^~!.=^'),`$/`
