===Gather=== Related to lazy evaluation is the construction of lazy lists using <code>gather</code> and <code>take</code>, behaving somewhat like generators in languages like [[Icon (programming language)|Icon]] or [[Python (programming language)|Python]]. <syntaxhighlight lang="raku"> my $squares = lazy gather for 0..Inf { take $_ * $_; }; </syntaxhighlight> <code>$squares</code> will be an infinite list of square numbers, but lazy evaluation of the <code>gather</code> ensures that elements are only computed when they are accessed.
