 it put the method in the cache (store empty info in the cache)

 it define the method getopts in Object (rb_cObject)

B> irb(main):003:0> getopts
B> NameError: undefined local variable or method `getopts' for
B> #<Object:0x807bd00> 

 it try to access getopts in self and first look in the cache and find it
 (empty info)

B> (irb):3:in `irb_binding'
B> irb(main):004:0> method :getopts

 1) it search the method body (but don't try first to access the cache)
 2) it find it in the Object
 2) it put the method in the cache

B> irb(main):005:0> getopts
