> Can somebody enlighten me what this is about?

Just a guess ... This might be related to the "newish" feature of having a special variable holding the reference of the current sub to facilitate recursions.

Unfortunately I wasn't able to find it again in order to test if it has issues with older sort implementations.

update

__SUB__ it was.

not a variable though ...
