Small correction:

ae = 'a'..'e'

ccae = ['<', *r, '>'] # => ['<', 'a', 'b', 'c', 'd', 'e', '>']

I'm guessing *r in the second line should have been *ae (or ae in the first line should have been named r)

Also

"It is new possible" should prpbably have been "It is now possible"

I'm pretty sure HN is not the place to post corrections for an article; have you tried any of the channels on https://crystal-lang.org/community/ instead?
