so far I have never noticed chain.from_iterable, but many thanks to
you Peter, I have now a beautiful solution to this problem.
>>> from itertools import chain
>>> comb = it.combinations(dims, 2)
>>> l = chain.from_iterable(it.imap(get_products, comb))
>>> l.next()
[('special', '+'), ('number', 1)]
>>> l.next()
[('special', '+'), ('number', 2)]
