macro programming in Lisp would be "programming programs". I don't see it here. This looks like compile-time execution to compute values. If it would be a macro, it could return source code.

Reader macros are there to program and configure the reader . The reader is responsible for reading s-expressions into internal data structures. There are basically two main uses of reader-macros: data structures and reader control. A CL

Message passing means that objects communicate only via messages with some payload. There is a sender and a receiver. Possibly there are many receivers in a broadcast message. Messages will run synchronous or asynchronous. The receiver deci
