1.7.3 CQL Simple DELETE

{[],
 delete(se_lt_x, [x_pk-I])}

Note that the WHERE clause is part of the delete/2 term unlike update where the WHERE clause is defined outside the update/2 term. I could have made delete consisent with update, but this would have required the @ alias in the delete WHERE clause to identify the table where the rows are to be deleted). This seems like overkill because a delete can in fact refer to only one table anyway i.e. you can't identify rows to delete via a JOIN.
