Fair, in this case my feelings are they are also easy to read and understand, compared to alternatives. Similar behavior implemented with text parsing, or annotation, or pre-processor, or inside the compiler, the code to implement them is a lot less tractable. Once you know how to write macros, it becomes fairly easy to also look at the implementation of a macro and figure out what it does. Macros tend to be very self-contained and often relatively short in implementation.
