 Hi there,
 Enumerators seem to be broken in trunk (did not try 0.2). Perhaps I'm
 using them the wrong way but anyways "at least it should not crash"
 (greetings to lrz).

 '''Code sample:'''
 {{{
 arr = [:a, :b, :c, :d]
 enum = arr.map!
 while(el = enum.next) do
  puts el
 end
 }}}

 '''Output:'''
 {{{
 foo.rb:4: [BUG] Segmentation fault
