Hello everyone,

I am currently writing a script to report on problematic entries in our company project management software's address list. I want to emit a a report in plain text, using Perl6::Form if possible. So far, it is mostly working, except for reporting entries with duplicate email addresses. While traversing the database, I gather duplicate email addresses in to a hash of lists, where the keys are the email adresses and the respective lists contain the names of the people who have that address listed.

I would like the output to look something like this: 
+------------------------------------------------------------+
| fake_address1@example.com              John Doe            |
|                                        Jane Doe            |
|                                                            |
| fake_address2@example.com              John Doe            |
|                                        Jane Doe            |
...
Currently, I am calling form like this: 
my %table = get_duplicates(); # More complicated, but you get the idea
+.
my @addresses = sort keys %table;
my $report = form {bullet => '*'},
'+-----------------------------------------------------------+',
'| {[[[[[[[[[[[[[[[[[[[[[[[[[[[}   * {[[[[[[[[[[[[[[[[[[[[[} |',
\@addresses, [map { $table{$_} @adresses],
'|                                                           |',
'+-----------------------------------------------------------+';

When I my script, however, the output looks more like this: 

+-------------------------------------------------------+
| fake_address1@example.com           ARRAY(0x12345678) |
|                                                       |
| fake_address2@example.com           ARRAY(0x90abcdef) |
...
I do get what is happening here, but is there a way for Perl6::Form to format my data the way I want it to?
I could use a full-blown templating library instead of Perl6::Form, but I would really prefer not to.
Is my approach entirely mistaken or am I just missing a minor detail?
Thank you very much for any insights you might feel like sharing with me!
