more cpan metrics
For a while, I’ve been keeping track of the total usage of my code on the CPAN. It helps me see what people have found useful, and lets me decide how scared to be of introducing back-incompat changes. Sometimes people talk about the sort of catastrophe that can occur if a highly-required module is broken. For example, over 11,000 dists require the code in Getopt-Long. If it broke badly and people installed the new code, it would be a nightmare.
