Examples

1. Due to the deficiencies of a purely syntax-rules based macro system, low-level macro systems have also been proposed and implemented for Scheme.
2. Others have proposed alternative uses of macros, such as anaphoric macros in macro systems that are unhygienic or allow selective unhygienic transformation.
3. Implementations of the hygienic macro system, also called syntax-rules, are required to respect the lexical scoping of the rest of the language.
4. Due to the deficiencies of a purely syntax-rules based macro system, low-level macro systems have also been proposed and implemented for Scheme.
