Twenty years ago...
Twenty years ago today I released my first CPAN module: Fork::Queue.
Then there was a group of people supervising module names, and they advised me to move it under the Proc namespace and so it became Proc::Queue.
A couple of weeks before, a bug on one of my scripts had fork-bombed a production box. I barely remember the details now... just that my manager had a serious conversation with me about the incident.
Anyway, that forced me to write the module.
Something I remember for sure is the proud I was of it. How I had been able to replace several Perl builtins playing with the CORE::GLOBAL namespace in a (IMO) clever way!
