Query: Will Wonders Never Cease?

The first Perl book I've seen that is truely great for beginners, great for people who are already Perl programmers, has a lot of example code, is a great reference, has a good reference section, and also seems to not leave any important details/sections out. The fact that it is very well organized/divided is definately a plus! Any person who wishes to learn Perl or have a great reference, MUST have this on their bookshelf.
