For the sake of the Perl historians, it would be nice to properly
attribute these inventions.
The table below is based on wild guesswork. If there are any oldbies
listening, please chime in with corrections.
Secret Operator Inventor Year
--------------- -------- ----
@{[]} aka ??? The Schwartz early 1990s
}{ aka eskimo greeting The Abigail late 1990s
=()= aka goatse ???
-+- aka spacestation The McGlinchy ???
~~ aka inchworm ???
~- aka inchworm-on-a-stick The Hospel 2002
We could also classify golfing techniques:
Golfing Technique Inventor Year
----------------- -------- ----
$_ x= boolean expression The Larry early 1990s
y///c aka Abigail's Length Horror The Abigail late 1990s
stuff value into $\ for printing The van der Pijll 2001
}for(...){ variation of eskimo The Hospel 2001
--$| magical flip-flop The Hospel 2002
\$h{X} is one less than ++$h{X}
aka Thelen's Device The Thelen 2002
-i and $^I for data value The Sperling 2002
Notice that some of the secret operators above also double as
golfing techniques. I'm sure there are plenty of other golfing
techniques I've forgotten because I am so rusty.
