## (Baggy) method Set

# class Any

From Any

## (Any) method Set

Defined as:

method Set(--> Set) is nodal

Coerces the invocant to Set, whereby Positionals are treated as lists of values.

# 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 = (:42a, :33b);say ; # OUTPUT: «[a => 42 b => 33]»say .Set; # OUTPUT: «set(a b)»

The set will be composed of the `key`

s 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.
