puts nil outputs "nil". Shouldn't it output "" (ie, nothing), which is nil.to_s? RDoc (for IO#print, referenced by #puts): Objects that aren't strings will be converted by calling their to_s method

The source code specifically checks for the nil object and outputs "nil" instead of nil.to_s . It's clearly a deliberate decision by the developers to make nil a special case. The docs don't mention it, and I agree that they should. Regards, Jeremy H.
