X::Obsolete Reference

Compilation error due to use of obsolete syntax

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 old #

method old(--> Str:D)

Returns Str:D.

Returns a textual description of the obsolete syntax construct

method replacement #

method replacement(--> Str:D)

Returns Str:D.

Describes what to use instead of the obsolete syntax.

method when #

method when(--> Str:D)

Returns Str:D.

Returns a string describing the state of the language (usually " in Raku").

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.

3 no-output
