I ran into this gotcha before: after calling
randomize(0),rand(int)generates 0 forever; this PR enforces that seed is nonzero to avoid puzzling behavior.#10546 (comment) added a documentation for the fact that
seedneeds to be nonzero but this PR enforces this with adoAssert.I'm not sure there's any valid use case for
randomize(0)(which generates constant, non-random data) but if there is one, IMO it'd be better via a different API, eginitNonRandom()or another name, otherwise it's error prone (easy to miss this point in docs)
