From the rdoc of IO#puts (http://www.ruby-doc.org/core-1.8.7/classes/
IO.html#M000474) it states that puts "writes the given objects to ios
as with IO#print". So puts calls print.

Further, the rdoc for IO#print ssays that objects passed to it "that
aren‘t strings will be converted by calling their to_s method."
