I'm sure I read somewhere about these issues, from an initial Googleing I conclude many have sought solutions to similar situations, I guess it is not so easy to decompile but it is just not impossible too knowing the compiler employed to accomplish the task and having a certain level of technical abilities, it'd be lucky if the compiler was not so advanced... check this node: Perl Decompile and PerlApp decompile?, even these discussion can have some insights.

Why don't you try to convince her to tell you more, or talk her into it? probably pay her ?!, encourage her ?! take her out to the nearest YAPC or whatever it takes...
