When passing new values for an attribute '@​.fields' as named parameters while cloning, the cloned object has the value of '@​.fields' as a Parcel instead of an Array​:

$ perl6-j -e 'class Foo { has @​.fields; }; my $x = Foo.new(​:fields<a b>); my $x2 = $x.clone(​:fields<c d>); say $x.fields.WHAT; say $x.fields.perl; say $x2.fields.WHAT; say $x2.fields.perl'
(Array)
["a", "b"]<>
(Parcel)
$("c", "d")

A similar problem exists for Hash/Pair​:

$ perl6-j -e 'my class Foo { has %.h }; my $b1 = Foo.new( h => "a" => "b" ); my $b2 = $b1.clone( h => "c" => "d" ); say $b1.h.WHAT; say $b1.h.perl; say $b2.h.WHAT; say $b2.h.perl'
(Hash)
{​:a("b")}<>
(Pair)
:c("d")

$ perl6-j --version
This is perl6 version 2015.06-217-g3776723 built on JVM

Moar gets this right. Please note that there is different code for Moar and JVM -- see commit rakudo/rakudo@7aa070e

There are two tests (fudged 'todo') in S12-attributes/clone.t.

This was fixed in rakudo commit 0c78181 and the test file now passes on R-J.

The RT System itself - Status changed from 'new' to 'open'

Thanks a lot! I'm closing this ticket as 'resolved'.
