[issue10109] itertools.product with infinite iterator cause MemoryError.

[Tim Peters]

Tim Peters added the comment:

I see nothing wrong with combinatorial generators materializing their inputs before generation.  Perhaps it should be documented clearly.  It's certainly not limited to `product()`.  For example,

>>> for i in itertools.combinations(itertools.count(), 2):
...	print(i)

dies with MemoryError too.  But I expected that ;-)
