serQ v0.1.0-rc8

--def NAME=expr (pyserq: compile(..., defs={"NAME": "expr"})) gives an expression def its body from outside, as --set gives a let its value: the program is the one written with that body, IR and all. A distribution, a key or a law per class the program leaves open under a name is a parameter of the run, where it had to be spliced into the program's text. The body may draw, read attributes and use the definitions before it; statement definitions and unknown names are errors; rejected on .json (#186).

pyserq Rng(seed): the generator a run draws from, rand 0.9's StdRng (next_u32, next_u64, random_f64, range_u64/range_u32/range_f64 with both ends included). A run seeded s draws its arrivals from Rng(s) (#185).

A NaN constant's error points at the expression when it has a place (#184).

IR version 9, as in rc7. No breaking change.
