It's * instantiated, but not ** instantiated, so the iterators buried
in the .specs of the list aren't forced to evaluate yet. And ranges
are iterator objects. The hidden iterators of a * list are evaluated
when the values are requested from the slurpy array. So

ought to produce lots of output without ever running out of memory.
(In reality, iterators are allowed to produce their values in batches
for efficiency, so there's a slight possibility that an iterator
could exhaust memory while producing the next batch.)
