* Extend rangrange() to return meaningful results when the range is
larger than 2**53. Only applies to the MersenneTwister. WichmannHill
was left alone in the absence of a proof showing how multiple calls
could be combined to produce long bit streams.
* WichmannHill was missing from __all__.
PlaySoundTest.test_alias_fallback(): Disabled this test, and explained
why in a new comment. My home Win98SE box is one of the "real systems"
alluded to (my system "default sound" appears to have vanished sometime
in the last month, that's certainly not a Python bug, and the MS
PlaySound docs are correct in their explanation of what happens then).
random.sample() uses one of two algorithms depending on the ratio of the
sample size to the population size. One of the algorithms accepted any
iterable population argument so long as it defined __len__(). The other
had a stronger requirement that the population argument be indexable.
While it met the documentation specifications which insisted that the
population argument be a sequence, it made random.sample() less usable
with sets. So, the second algorithm was modified to coerce non-indexable
iterables and dictionaries into a tuple before proceeding.
