Perl5porters wants us to believe that they care a lots about backwards compatibility. This is, however, not true, as shown by how many of my obfuscations doesn't work anymore with recent perl versions, or they give warnings even when you don't enable warnings.

This node tries to be a comprehensive listing of which of my obfus still work and which don't. I'll try to update this node with newer breakage in the future.

This trend is also not specific to the obfu I write. The following section is of course just a selection, but you monks are encouraged to post tales about your broken code in replies: then maybe p5p will listen to us and stop these incompatible changes if they hear enough people complain. (Yes, I'm not completely serious, but this is the obfu section so I don't have to say that, right?))
