X::Syntax::Reserved Reference
Compilation error due to use of syntax reserved for future use
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 reserved #
method reserved(--> Str:D)
Returns Str:D.
Returns a text description of the reserved syntax.
method instead #
method instead(--> Str)
Returns Str.
Describes what to use instead of the reserved syntax (if anything).
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.
