A few comments… 1. It would be nice to do a bit of documentation on *why* or *how* some of these work. Perhaps a Deparse would be sufficient (as in Eskimo greeting), but English is also a good tool. For starters, I didn't figure out how Ornate double-bladed sword worked. I'm sure I could have created the trail alone, but it would be nice to follow someone else's blaze. 2. Given how dangerous this one could be (to a psyche) if researched deeply (years of therapy…) =( )=Goatse scalar / list context I'd suggest another name -- Saturn. Yes, snicker if you will. Saturn *is* the son of the Greek deity Uranus, but that's only a 2nd order, inside joke. The operator looks like Saturn, even when spaces are inserted (as will be likely with syntax formatting editors or perltidy(1))! =( )=Saturn scalar / list context = ( ) = Saturn scalar / list context Keep the old name if you wish, but add one that's more psychologically healthy, too!!!

Re: Secret operators: the documentation
I wonder if --$| and $|--, very popular in golf, and described by japhy as the magical flip flop variable at: http://www.nntp.perl.org/group/perl.fwp/2002/01/msg1367.html qualifies as a secret operator? /-\

It sounds that it won't fit well in the official Perl documentation ;) I've pushed a branch on the Perl source tree, and Abigail already patched the module a bit. http://perl5.git.perl.org/perl.git/shortlog/refs/heads/book/perlsecret The word of warning still holds. The page is specifically not listed in the main perl.pod manual page. The idea is to hide it a little, so that people who know about it can easily point inquiring minds to it, while not making these official. I also wrote a test script (t/japh/secret.t) and it helped a lot in refining exactly how and when each of those worked. -- Philippe Bruhat (BooK) Did I err?

I have had several requests for adding more obscure constructs (see https://github.com/book/perlsecret/issues). My rule has been to keep only the well-known operators, or the ones that had a nickname that corresponded to their looks, not their function. Under that rulle, the magical flip-flop wouldn't have fit. Anyway, I guess others can decide what gets in when the branch merged into blead. -- Philippe Bruhat (BooK) Out of the worst can often come the best. (Moral from Groo The Wanderer #57 (Epic))
