This is ~500 lines of code that we don't need in the main Rand crate IMO. (The reason
WeightedIndexis there is that it is used by theseqmodule; but thealias_methodvariant is not since it's initialisation cost makes it completely inappropriate for this single-use API.)Question: should we deprecate the
weightedpub module inrand, since this module doesn't need to be public now? (I guess this might require some re-exports or something internally, but we can do it.)Similarly, the
weightedpub module andalias_methodsub-module inrand_distrseem somewhat unnecessary.
