or better:

h = { a: ["A"] * 5, b: 0, c: 1 }

I never understand ppl's obsession with Array.new and Hash.new, not including hash's block initializer. Hash.new {...} is brilliant and I love it. I think all variants or Array.new are essentially useless and stick to [] for everything.

Most of my students who Array.new that were Java developers and it was pretty easy to break them of the habit.

(and most of my students who obsessively used '' instead of "" were perlers... that was a harder habit to break, even if I could show them that they were just as fast (and always faster than perl)).
