[PD] An Iterator object

Hello all,

I am looking for an object that will create any number of "embedded" iterators. The best analogy would be having a bunch of embedded "for" loops, like this:

for (i = i_init; i < i_limit; i += i_inc) for (j = j_init; j < j_limit; j += j_inc) doSomething();

I have created an abstraction that acts as a single loop, and I am using "until" to control the loops iterations. I would like to be able to not use "until" as this forces a restriction of making sure that all operations be performed within the same "time-interval" as all others. I would like to be able to send a single bang to the "top of the loop", and have it output the next set of iterators. For example

[iterator 0 10 1 100 1000 100]

banging on the iterator would produce the follow excerpt:

  0 100
  0 200
  ...etc
  0 1000
  1 100
  1 200
  ...etc

Is there an external that does something like this?

Thanks,

Mike
