Abstract

this document without fee provided it is copied in its entirety and this notice remains attached. the computation and communication of an operation on the data type are arranged. That's a job for the implementer and compiler writer. So there's a separation of concerns at just the right level --- programmers think about monolithic operations on data types, while implementers worry about how to make them happen. This provides architecture independence. If the target machine is replaced during the night by some new machine, even a completely different architecture, there is no need to alter the software. The differences between machines can be hidden by the compiler.
