You know what's interesting is the way in which B::Deparse breaks this obfu. In specific, Deparse breaks the portion that goes like this: $|[ $a++ ] = chr $;;. Deparse turns that into $|[ $a++ ] = chr $;. The important difference is the missing statement terminator, ';'. After being deparsed, until I manually add that back in, I get the following: 

Scalar found where operator expected at mytest2.pl line 16, near "$;
        $;"
        (Missing operator before $;?)
syntax error at mytest2.pl line 16, near "$;
        $; "
Execution of mytest2.pl aborted due to compilation errors.

I know the old mantra is "Only perl can parse Perl", and this is an example of that being the case. I'd say it's a bug in B::Deparse, but then we can't expect it to be perfect, especially when presented with an obfu. I'm just surprised that it got tripped up by something so trivial as a statement terminating semicolon.
