in reply to callback for regex engine

I was wondering if there is a capability in Perl to register a call back to the regex engine and call that registered function each time a particular match is made.
This might be of interest:
s///e and s///ee allow you to execute arbitrary any code (presumably including function calls) for each match
See s/PATTERN/REPLACEMENT/msixpodualgcer in Regexp Quote Like Operators (you have to go down a few pages): 
e  Evaluate the right side as an expression.
ee Evaluate the right side as a string then eval the result.


UPDATE: s/arbitrary/any/

    [I was confused by the term "arbitrary code", which is normally used to refer to how s///ee can execute code found in data. Ignore this post.]
