Julian Hyde commented on CALCITE-1309:
--------------------------------------

> {code}
> SELECT MyTable.*, t.s  FROM MyTable, LATERAL TABLE(split(MyTable.a)) AS t(s)
> {code}
> will throw “Encountered "LATERAL TABLE" at line 1, column 38.” exception. 
> We should support LATERAL TABLE ,  and allow table function to see earlier tables in the FROM clause.
