🤔 would a multi-join work for a query like
```sql
SELECT ..
FROM A JOIN B ON (a.x=b.x)
JOIN C ON (a.y = c.y AND b.z = c.z)
```
A join graph might look like this
```
(A) -- y -- (B)
\ /
x z
\ /
(C)
```
Would a multi-join look like
```
JOIN (a.x=b.x, a.y=c.y, b.z=c.z)
(A, B, C)
```
I guess then any reordering could happen as a translation from Multi-join to
binary join 🤔
