Thanks for sharing. While the original C preprocessor can be a pain (but is still useful to have), additional pre-processors can add language features without abandoning the C standard and one's tool chain. One issue is that other developers need to either learn the dialect accepted by the preprocessor or make sense of its output. Here I think some good decisions have been made: Pros: + safer code + shorter/more concise code Cons: - learning curve of the pre-processor Objective C and C++ started out as pre-processors, of course... ;)
