Information is obtained in many ways, young grasshopper. {grin}
Most of Perl is documented by the originators, better than most things I've had to wrangle.
Many of the books out there contain good stuff, but many more contain
bad stuff. Trust is important, or experimenting or cross checking for
verification.
You can "ask an expert", either directly (usually for pay) or in a community
setting, like the Monestary, IRC, or Usenet.
Or, you can just bang on it a bit yourself until you find out that it breaks (or doesn't)
to your satisfaction.
There's nothing I know that wasn't found out from one of the above. It's not rocket
science (but even rocket science fits the above {grin}).
