According to:

 http://www.nntp.perl.org/group/perl.fwp/3727

the @{[]} "secret operator" was invented by Randal and/or
Larry in 1994.

BTW, cog dreamed up a (presumably) vulgar name for the @{[]}
operator, as alluded to here:

 http://www.nntp.perl.org/group/perl.fwp/3726

I don't know what this name is though.
