Macros

We can use macros to define our own special forms. We can see what a macro expands to by placing the point on the closing parenthesis and running pp-macroexpand-last-sexp.

Macros are a way to reuse or inject code into your logic flow. Arguments passed to functions are evaluated before the function is called but with macros you can pass arguments that the macro chooses when to evaluate.
