X::Anon::Multi Reference

Compilation error due to declaring an anonymous multi

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 multiness #

method multiness(--> Str:D)

Returns Str:D.

Returns a string describing the multiness that the original code used, for example "multi" or "proto".

method routine-type #

method routine-type(--> Str:D)

Returns Str:D.

Returns a string describing the type of routine that was declared, for example "sub" or "method".

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.
