(Parameter) method sigil §
Defined as:
method sigil(Parameter: --> Str)Returns a string containing the parameter's sigil, for a looser definition of "sigil" than what is considered part of the parameter's name. Still returns a sigil even if the parameter is anonymous.
This "sigil" is actually an introspection used to help determine the normal binding style of a parameter, if it has not been altered through a trait.
| Sigil | Will bind to | Default behavior |
|---|---|---|
| $ | Scalar | Generate new Scalar, use instead of Scalar in argument, if any |
| @ | Positional | Bind directly to the argument |
| @ | PositionalBindFailover | If binding failed, call argument's .cache method, bind to result |
| % | Associative | Bind directly to the argument |
| & | Callable | Bind directly to the argument |
| \ | (anything) | Bind directly to the argument, keep existing Scalar, if any |
Also, | will bind to all remaining arguments and make new Capture if needed.
