Editing Raku (programming language) (section)

===Syntactic simplification===<!-- This section is linked from [[Ellipsis]] -->
Some Perl constructs have been changed in Raku, optimized for different syntactic cues for the most common cases. For example, the parentheses (round [[bracket]]s) required in [[control flow]] constructs in Perl are now optional:<ref name="syn04"/>
<syntaxhighlight lang="raku">
if is-true() {
    for @array {
        ...
    }
}
</syntaxhighlight>
Also, the <code>,</code> (comma) operator is now a list constructor, so enclosing parentheses are no longer required around lists. The code
<syntaxhighlight lang="raku">
@array = 1, 2, 3, 4;
</syntaxhighlight>
now makes <code>@array</code> an array with exactly the elements '1', '2', '3', and '4'.
