| documentation: |
--- Combines two transactions into a single transaction that executes --- both in sequence. The first transaction is executed, its result --- passed to the function which computes the second transaction, --- which is then executed to compute the final result. --- --- If the first transaction is aborted with an error, the second --- transaction is not executed. |
