[issue40806] itertools.product not lazy

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

Updated the docs to note that inputs are fully consumed before the iterator is run.

FYI, notes on infinite iterable inputs likely belong the FAQs because they aren't specific to product().  Similar effects would be seen with list(x(1)), sorted(x(1)), set(x(1)), tuple(x(1)), etc.
