16.2 General Macro Transformers🔗

The define-syntax form creates a transformer binding for an identifier, which is a binding that can be used at compile time while expanding expressions to be evaluated at run time. The compile-time value associated with a transformer binding can be anything; if it is a procedure of one argument, then the binding is used as a macro, and the procedure is the macro transformer.
