Course of Raku / Essentials / Positional data types
Quoting string arrays
For string arrays, where the items are short strings with no spaces, Raku offers a nice syntax for initialising them.
my @digits = <zero one two three four five six seven eight nine>;
It is up to you to decide to add additional spaces around the angle brackets or not. The compiler accepts both options.
my @digits = < zero one two three four five six seven eight nine >;
Both constructions are equivalent to a straightforward variant:
my @digits = 'zero', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine';
Array vs List
Notice that in the examples above, the quotation < . . . >
creates a List
, not an Array
. You can confirm it by calling the WHAT
method:
say <a b c>.WHAT; # (List)
Nevertheless, when you assign it to an array, you get an array with the elements from the list.
my @a = <a b c>;
say @a.WHAT; # (Array)
