Thanks for the comments. I fixed the wording mistake of 3.99 being an integer. You are right about everything you say. @{[]}, <=>, and =()= are acceptable in production code, but the others are not. These other "operators" actually were invented to chop off characters in Perl Golf competitions. This article wasn't meant as "good Perl coding tips and tricks", it was more written for fun.
