Raku highlighting

class X::Inheritance::Unsupported does X::Comp { }

Compile time error thrown when trying to inherit from a type that does not support inheritance (like a package or an enum).

For example

Raku highlighting

enum A <Ax Ay>;
class B is A { };

dies with

｢text｣ without highlighting

===SORRY!===
A does not support inheritance, so B cannot inherit from it
