The rule for kebab-case (regardless of whether or not it has a sigil) in Raku is: - each part of the identifier must start with an alpha character - cannot end with - So, "foo-bar" would be legal, "foo-" would not, "foo-4" would be considered "foo" - 4. If you want to substract two sigilless identifiers, you *must* have whitespace between them. So "foo - bar" instead of "foo-bar".
