Practical Perl Tools: Constant as the Northern $*
David N. Blank-Edelman
The bad Perl wordplay in the title can mean only one thing: We have another column about programming in the Perl language underway. This issue’s column is inspired and derived from an article I stumbled on by Neil Bowers. Back in 2012 he wrote an article on 21 different modules for defining constants in Perl. The original is at http://neilb.org/reviews/constants.html. If reading my take on his research gets you interested in the subject, do be sure to seek out his article. One other thing I should mention before we discuss his work: He’s clearly cooler than I will ever be. When he encountered some bugs in one of the modules he reviewed, he “took over maintenance of the module and released a new version which addresses all known issues.” Now that’s thorough!
