Proving that the Pascal part of my soul is not dead (merely resting), I was quite heartened to see that Ruby permitted the following syntax:
for i in 0..255
I miss Pascal’s syntax. I rather liked that you could start at any arbitrary number and end at any arbitrary number, inclusive — especially handy for arrays of things.
Ruby also adds the three dots syntax to exclude the last number: 0..255 = 0…256.
