As an aside, I've always found Perl's treatment of sigils confusing - especially when using hash slices!
So I applaud Raku's more uniform approach, amusingly explained by Damian Conway in
this youtube talk (9:45-10:40)
in the following two tables of which sigil to use when:
Perl | Scalar | Array | Hash |
Full contents | $ | @ | % |
Individual element | $ | $ | $ |
Multiple elements | @$ | @ | @ |
Multiple elements with keys | %$ | % | % |
Raku | Scalar | Array | Hash |
Full contents | $ | @ | % |
Individual element | $ | @ | % |
Multiple elements | $ | @ | % |
Multiple elements with keys | $ | @ | % |
I especially enjoyed TheDamian's quip at the 10:30 mark:
It really does make everyone's lives easier ... except for people who are
coding in both Perl 5 and Perl 6 at the same time. Your lives will be misery. :)

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).
