in thread reduce like iterators

In general and in theory, no.

But lots of people have so done, and it works out reasonably well in practice. For a random example Dominus used char(20) for this purpose in the widely used Memoize. (Then documented the limitation.) This code is significantly faster than a robust escape mechanism would have been, and he provided a mechanism to fix the potential bug if you needed to.
