I was thinking along the same lines too, but I had a different approach to it, which saved me three characters.

46 (but changes too much)
if we lookahead and lookbehind, we can lose the last "<!--$x-->" bit, and if we use $_ we can save 1 character from =~ and lose "my"
s/(?<=<!--)(.+?)(?=-->)/($_=$1);s|-||g;$_/seg

He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.

[james28909]: Good morning!
[james28909]: I have a problem I am trying to solve. I am packaging scripts using pdk and would like the verify the executable name each time it is executed
[Corion]: Hi James!
[james28909]: I looked through the docs, and see that PerlApp::exe() is suppose to return this information but whenever i try to use this, i get the error "Undefined subroutine &PerlApp::exe called"
[james28909]: i just want to verify the integrity of the executables name each time it is run.
[Corion]: Weird. this documentation says what you say.
[Corion]: I assume you are experiencing this with your packaged program. Maybe also include PerlApp.pm in the packaging list?
[james28909]: has anyone else run into this problem? i have tried searching but have not returned many results
[james28909]: ah, good idea.
[Corion]: What does print $PerlApp::VERSION output?
