Since otherwise I'd be hijacking, I'm starting a new thread on this:

Could you say why, Robert? Obviously there's more than one way to do
something, but I am interested in why you'd choose this way?

I don't very much like the previous Array.new() {} either, although
being 1-based might be easier for some to understand, but breaks my
oh-so-long-established zero-based array mentality. I'd have approached
this with #reduce. I'd appreciate hearing your thoughts on the
trade-offs.
