method is run, not once when the enumerator is initialized as it
was before, so that method_missing() and method (re)definition
afterwards are both in effect; pointed out in: [ruby-core:16441]

Add a new exception class StopIteration, which breaks Kernel#loop
iteration when raised; backported from 1.9.

ext/enumerator, common.mk (OBJS, enumerator.$(OBJEXT)): Make the
enumerator module built-in,
* enumerator.c: New method: Enumerable::Enumerator#with_index.
* enum.c (enum_each_with_index): Enumerable#each_with_index now
returns an enumerator instead of raising an exception if no
block is given. Enumerable#enum_with_index, formerly defined in
the enumerator module, is kept as an alias to each_with_index
for backward compatibility.
