Re^3: Substituting a comma only when it is preceded and followed by a bracket
in thread Substituting a comma only when it is preceded and followed by a bracket
Bravo. Code written in this way would be instantly apparent to anyone who encountered it, and of course it would make no difference to the Perl compiler.
I am a very big believer in writing code in this way, and also in keeping a daily “running log,” or diary, in which I talk to myself about what I am doing and why. Every developer on my teams is asked to keep an ongoing project diary within the repository and to review one another’s entries from time to time. You don’t remember nearly as much detail as you suppose, not even about things that you did and even that you did recently.
