5. Macros

Gauche supports both R5RS hygienic macros and traditional macros.

Macro of Lisp-family language is very different feature from ones of other languages, such as C preprocessor macros. It allows you to extend the original language syntax. You can use macros to change Gauche syntax so that you can run a Scheme program written to other Scheme implementations, and you can even design your own mini-language to solve your problem easily.
