Which non-Perl books made you a better (?:Perl )?Programmer?
The Art of Computer Programming, especially volume 2. I didn't realize how many difficult computational issues had already been analyzed and understood in depth.
Unix Haters, which makes me realize: There is always another edge case I've missed; and People will use my software in ways I didn't anticipate or intend, but I want it to behave well if possible.
Unix Power Tools, which informed me on the origins of Perl, and what kind of tools are already available on the underlying OS (or might be missing, depending on the flavor, whims of sysadmins, or non-Unix systems).
