Is chomp really worth a new class?  Note that you can do all of this
already with an IO:

$ ruby -e 'STDIN.each {|line| p line}'
dd
"dd\n"
ff
"ff\n"

$ ruby -e 'p STDIN.entries'
dd
ff
["dd\n", "ff\n"]

$ ruby -e 'p STDIN.map {|line| line.inspect}'
ddd
sss
["\"ddd\\n\"", "\"sss\\n\""]

Kind regards

robert
