It appears that Lee has updated several of these tests. I now pass
them all:

┌───────────────────────────────────────────┬────────┬─────────┐

│"Join operator with OPTs, BGPs, and UNIONs"│"passed"│!unbound!│
│       "Join operator with Graph and Union"│"passed"│!unbound!│
└───────────────────────────────────────────┴────────┴─────────┘
┌───────────────────────────────┬────────┬─────────┐
