 it define the method getopts in Object (rb_cObject)

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

 it try to access getopts in self and first look in the cache and find it

 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
