Are there any modules using source filter to capture code?

LanX has asked for the wisdom of the Perl Monks concerning the following question:

In continuation to Filehandle of the current sourcecode, pointing after last code line? I wrote some (non intrusive) code using Filter::Simple to the source of the current file (actually the lines after the use module )

It's a rather trivial idea but I couldn't find anything similar on CPAN .

Question: Did I reinvent the wheel or should I publish?
