Subject: overriding operator 'or'

According to "Ruby in a Nutshell" pg 18, 'or' is a nonmethod operator 
which cannot be overridden.  However, it seems that I CAN override the 
'or' operator:

irb(main):001:0> class Foo
irb(main):002:1>   def initialize(value)
irb(main):003:2>     @value = value
irb(main):004:2>   end
irb(main):005:1>   def or(other)
irb(main):006:2>     @value or other
irb(main):007:2>   end
irb(main):008:1> end
nil
irb(main):009:0> myfoo = Foo.new(1)
#<Foo:0x40202290  @value=1>
irb(main):012:0> p myfoo or 0
#<Foo:0x40202290  @value=1>
0
