X::Syntax::Variable::Twigil Reference
Compilation error due to an unallowed twigil in a declaration
What it is #
Routines #
Signatures are reproduced from the documentation, including their declared return types. A routine listed here is part of the type's published interface; whether Raku++ implements it is a separate question, answered by the examples below.
method twigil #
method twigil(--> Str:D)Returns Str:D.
Returns the twigil that was illegally used
method scope #
method scope(--> Str:D)Returns Str:D.
Returns the scope that did not harmonize with the twigil.
Examples, run three ways #
Every example below comes from the official documentation, together with the output that documentation asserts. Each was then executed by Rakudo and by Raku++ when this page was built. Where the three agree, one result is shown; where they do not, all three are — because which of them is wrong is exactly the information worth having.
