>
> Create an immutable version of {{{}class ListSqlOperatorTable{}}}, to be created via {{SqlOperatorTables.of(operatorList)}} or {{{}SqlOperatorTables.of(operator, ...){}}}. 
> {{class ListSqlOperatorTable}} still exists but its constructors and {{add(SqlOperator)}} methods are deprecated. We hope that people will create immutable operator tables most of the time.
> Refactor {{MockSqlOperatorTable}} to be immutable. Methods that mutate the table, such as {{addRamp}}, are replaced by methods that return a copy.
