Don't be. Its a common thought, and its noticed lack in Ruby is obviously one 
of the first things a Nuby will wonder about. And I certainly wouldn't expect 
a Nuby to know too much about tracking down past suggestions either.

Yes, yes it does. :)

POLS - Principle of Least Surprise. It is a general design principle by which 
Matz does his best to apply to the design of Ruby. By extension, Rubyists try 
to follow the same principle. Obviously we all have different opinions about 
it.

Duck Typing - An much newer notion that a class/object (even a method in a 
round about way) has a Type based on the the methods it responds to and not 
by the name it is given. This analogy may help:
 
  Class : Duck Type :: kind_of? : repond_to?
