X::ControlFlow::Return Reference

Error due to calling return outside a routine

What it is #

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.

return;
CATCH { default { put .^name, ': ', .Str } };

Raku++ disagrees with both the documentation and Rakudo — a defect.
