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 `type` #

method type(X::Bind::Slice:D:)

returns the type object of the thing that you tried to slice-bind, for example Array, List or Hash.

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.

Not executed: the documentation states no expected output for this example.

my @a; @a[0, 1] := [42];
CATCH { default { put .^name, ': ', .Str } };
# OUTPUT: «X::Bind::Slice: Cannot bind to Array slice␤»

X::Bind::Slice: Cannot bind to Array slice

Rakudo

Raku++

Both engines agree; the documentation states something else. Trust the engines.

my %h; %h<a b> := {};
CATCH { default { put .^name, ': ', .Str } };
# OUTPUT: «X::Bind::Slice: Cannot bind to Hash slice␤»
