Looking at Sets https://docs.perl6.org/type/Set
I was happy to see (-) to work as I expected, but I was surprised to see
that (+) created a bag. Is that intentional? How can I get back the
set. Is the only way using the unicode character ∪ ?
(This is Rakudo version 2017.04.3 so I might be behind the times on this.)
$ perl6
To exit type 'exit' or '^D'
> my $a = set('a','b')
set(b, a)
> my $b = set('a', 'c')
set(a, c)
> $a
set(b, a)
> $b
set(a, c)
> $a (-) $b
set(b)
> $b (-) $a
set(c)
> $a (+) $b
bag(b, a(2), c)
> $a ∪ $b
set(b, a, c)
