Can a Perl module "inspect" itself and provide details about methods and parameters?by Br'er Rabbit (Novice)

Br'er Rabbit has asked for the wisdom of the Perl Monks concerning the following question:
I'm suffering through an exercise to do some image processing with ImageMagick by way of PerlMagick (the Image::Magick Perl module).
The documentation is maddening (notwithstanding RLS's praise of it as "unimpressive"), and anyone who wants to do anything other than a simple example, will find theirself roundtripping from pillar to post.
Until reading his comment, I hadn't thought to look at the--shudder--source code,
...but my thoughts were running a different direction.
I seem to remember that Perl modules are "objects" or collections of them and I remember from the many attacks on my comprehension by "object-orientation" that "objects" can be ASKED this-or-that. (It's supposed to be a "feature.")
I also recall that they implement METHODS which can be public or private to make answer to queries.
...SINCE "objects" and "Perl modules" are way smarter than me, knowing way much more about their innard-parts than me, I would like to ask them:
"Hey, could you please TELL me what PUBLIC methods you have, and WHAT parameters they use, including their DEFAULTS?"
Kinda like: "Hey, why don't you read your own damn source code and highlight the most important bits for me?"
If they would just do that, I would write their answers down and tape them to the stupid monitor and stop all this hunting around.
Thank you for your time. Peace.
