Hello,
$ perl6 --version
This is Rakudo version 2016.04 built on MoarVM version 2016.04
implementing Perl 6.c.
Reading http://doc.perl6.org/language/classtut
suggests that the dot twigil provides read-only access to the attribute.
But it is possible to change Array and Hash:
$ perl6 -e 'class A { has $.wut = [] }; my $a = A.new; $a.wut =
[1,2,3]; dd $a;'
A $a = A.new(wut => $[1, 2, 3])
I was expecting something like 'Cannot modify an immutable Array'
$ perl6 -e 'class A { has $.wut = set() }; my $a = A.new; $a.wut =
set(1,2,3); dd $a;'
Cannot modify an immutable Set
in block <unit> at -e line 1
