Not at all.  I had thought about the limit myself but did not want to 
bother implementing it.  Two remarks about your code:

You include Enumerable but do not provide #each which is required.

You use instance variables for the iteration which is a bad thing 
because this needless restricts usability (namely in the light of 
multiple threads).  Array and other's also do not store the iteration 
state in instance variables but in local variables in method #each.  You 
can try it with something like this which would not work if instance 
variables would be used for storing iteration state

a=(1..10).to_a
2.times {|i| Thread.new(i) {|j| a.each {|x| puts "[#{j}-#{x}]"; sleep 0.5}}}

Kind regards
