class List

From List

(List) method Set

In general, creates a set which has as members elements of the list.

say <æ ß þ €>.Set ;# OUTPUT: «set(ß æ þ €)␤» 

However, there might be some unexpected changes in case the list includes non-scalar data structures. For instance, with Pairs:

my @ary = (:42a, :33b);
say @ary.Set;# OUTPUT: «set(a b)␤» 

The set will be composed of the keys of the Pair whose corresponding value is not 0, eliminating all the values. Please check the Set documentation for more examples and a more thorough explanation.
