I recently added a script called MODULATOR
(updated) to the catacombs and have a question about the unexpected results of one of its functions. When viewing POD this script optionally puts the example code from the "synopsis" section into a form so it can be tested using eval. This works well most of the time but the Acme
brand of modules is causing problems. If the example code from say Acme::Bleach
print "Hello world";
is evaluated, the modulator script is wiped out and replaced with the output of Bleach, namely a file full of invisible characters with "use Acme::Bleach" at the top, and it ceases to function at all.
- Is there a way to prevent this unfortunate outcome besides preventing certain naughty modules from the eval?
- Are there any other modules besides the Acme brand that involve this kind of danger to the invoking script?
Thank you for your consideration of this matter.
