The rc file used to be a bunch of variables, each one requiring to be declared before being used. While this was nice and all, it was a little cumbersome to add a new flag or option. If you disregard the "catch typos" aspect of having to predeclare variables, it's a lot more useful to have all of rc be in a hash and use any hash keys you want. There could be other uses; for instance it could hold arbitrary data that you would currently put in %ENV, without having to pollute %ENV if you don't need child tasks to inherit it. ---- NOTE: I also ran perltidy, which I don't always remember to :)
