From: Brian Candler Date: 2004-11-06T22:45:34+09:00 Subject: puts nil generates "nil\n" $ ruby -v ruby 1.8.2 (2004-07-29) [i386-freebsd5] $ ruby -e 'puts nil' nil $ ruby -e 'puts nil.to_s' $ This is strange and seems to conflict with the documentation in ri, which says: - Kernel.puts is the same as $stdout.puts - IO.puts says Writes the given objects to _ios_ as with +IO#print+. - IO.print says Objects that aren't strings will be converted by calling their +to_s+ method. So is 'nil' a special case for puts/print? Is the documentation wrong? Regards, Brian Candler.
