-The macro capabilities of C3 reaches across several constructs: macros (prefixed with `@` at invocation), [generic functions, generic modules](/generic-programming/generics/), and [compile time variables](/generic-programming/compiletime/#compile-time-values) (prefixed with `$`), macro compile time execution (using `$if`, `$for`, `$foreach`, `$switch`) and attributes.

 A macro is defined using `macro <name>(<parameters>)`. All user defined macros use the @ symbol if they use the `&` or `#` parameters.
 
 The parameters have different sigils: `$` means compile time evaluated (constant expression or type). `#` indicates an expression that is not yet evaluated, but is bound to where it was defined. Finally `&` is used to *implicitly* pass a parameter by reference.
