# I'm wondering if there's a better way to do this in ruby:
# if a == "word1" || a == "word2" or || a == "word3"
#   puts "good"
# end

ruby allows you to beautify ;)

good

fwiw, sometimes in cases like this, i start off with a... case,

> case a
> when "word1", "word2","word3"
>   puts "good"
> end

then just sprinkle w more cases, and  beautify as i go...
