Thanks for the discussion everyone...I always do my homework first, but the web has just as many bad examples and poorly written documentation as it does good ones. In any case, the goal here is for all of us, particularly myself, to become better programmers. To that end, since I didn't find any examples as unique as Almut's use of the unpack function, do I understand its use thusly:

return - we want to return a value
map - we're going to use the map function to evaluate each array node
"AP" . join "." - I understand what this is doing, but I don't understand from any documentation what the first argument to map is, generally speaking (everything before the first comma)
unpack - I see from documentation that the capital 'A' for unpack refers to any ASCII character with its whitespace, but again I don't understand from documentation that you can add the ordinal and/or * along with it, and how that modifies the query
lc $_ - perform the lowercase operation on the current scalar/node of the array
@_ - Store the results to the unnamed array @_

If anyone has any additional comments and/or suggestions regarding my understanding, please feel free. In addition, any suggestions for comprehensive documentation is appreciated. I currently use search engines to find as many examples of a particular piece of code until it clicks with me and I understand it.

Regards, Scott
