Danny Chen commented on CALCITE-4899:
-------------------------------------
The use case you provide sounds valid from my side, what i'm wondering is if
there is existing vendor has similar syntax for lateral table hints, so that,
when design the grammar, we can make it more in line with the other vendors,
not to make to syntax looks weird, i mean.
