Bandwidth exceeded. Can I suggest this would make a good meditation? Perlmonks has more bandwidth than your site, almost certainly.

Since I can't see the list:

  1. When would yo prefer a hash to an array, and vice versa? Why, in each case?
  2. What's your favorite CPAN module? Why? What would you change about it?
  3. Do you have any modules on CPAN? What do they do?
  4. Explain how objects and inheritance work in Perl.
  5. Explain what references do and how they work.
  6. When would you prefer a plugin/delegation architecture to an inheritance-base one? Why
I'll probably think of some more.

[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.
