X::Cannot::Lazy Reference

Error due to inappropriate usage of a lazy list

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 action #

method action()

Verbal description of the inappropriate action.

method what #

method what()

Returns the type that was the target of the action, if it was not the lazy list itself.

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.
