I don't quite agree with this table. Please consider the following code.

constant term:<$container> = 1,2,3;

say $container, $container.WHAT; # (1 2 3)(List)
say "answer: $container"; # answer: 1 2 3
dd $container; # (1, 2, 3)
               # note the lack of naming of the container

sub s($first, *@rest){
    dd $first, @rest;
}

s($container); # $(1, 2, 3)
               # Array element = []

Here, $container is not a container. It is a List of Values and also a scalar. In quote interpolation it is handled like a list but in a signature as a scalar. In plain Raku (not in a signature, not in a quote, regex, etc.) '$' may not indicate Scalar.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
