Set functions
=============

Seam: set0 through set2, captured choices, free arguments and nested sets.
Values is a finite multiset; sortValues fixes the order for comparison.

Run ./run after make stage, or run unit_boundary.py from tests/.
The run script selects the staged Python and the session backend.
expected.out records stdout; stderr is shown on failure by the test.
The driver comments explain the individual probes and their order.
The corpus README.md lists the backends and the oracle for this driver.
