This is an oft-reported TODO, but one that's stalling on other future
improvements to the quote parser. In the meantime, you can interpolate
arrays and hashes through closures.
$ perl6 -e 'my @a = 1; say "{...@a[0]}"'
1
$ perl6 -e 'my @a = 1; say "{...@a}"'
1
$ perl6 -e 'my @a = 1,2,3; say "{...@a}"'
1 2 3
$ perl6 -e 'my %h = one => 1; say "{%h}"'
one 1
$ perl6 -e 'my %h = one => 1; say "{%h<one>}"'
1
$ perl6 -e 'my %h = one => 1; say "{%h{"one"}}"'
