I'm aware of this, but thats exactly why I was describing a call-back function to control the process.

For instance the filepath could be taken to make a distinction between trusted and new code.

And rurban's suggestion to wrap the code into a Safe environment could be chosen to allow execution of BEGIN blocks in untrusted code.

Tell me, PPI can find BEGIN-Blocks like in ''=~('(?{B'.'EGIN{print "owned"}})') ?

AFAIK PPI can not deal with all kinds of syntax changing mechanisms. So wouldn't be of much help when searching for evil code, since attackers could use these limitations.
