First line while (line = gets) would be better Ruby as
while line = gets.
Even Scala 3 has been Rubyfied and suppressed these parentheses ! :slightly_smiling_face:
(In Programming Ruby 1.9 2010 edition p.24 there were no parentheses)

Same in Reading and ‘Riting page 30 :

while (line = gets)
print line
end
