There were some interesting answers, yes. However, the real title for the book is:
Obfuscation,
Golfing, and
Secret
Operators in
Perl
My Publisher is Onyx Neon Press, my editor is Allison Randal, and the book's mailing list is here.
When is it coming out? I have absolutely no idea at the moment. It will probably take at least a year (but maybe less). In the meantime, you can join the mailing list.
