Data::Pretty
When you stringify Perl 6 data structures, you expect sensible results just
like in any modern programming language. Unfortunately, Perl 6 doesn't deliver
on that point; it hasn't shaken off all the weird legacy stringification from
Perl 5.
$ perl6
> [1, 2, 3] # no brackets :(
1 2 3
> (1, 2, 3) # no parens :(
1 2 3
> [1, 2, [3, 4]] # can't see the nesting :(
1 2 3 4
> /abc/ # regexes don't say much :(
> sub foo {} # long ugly number :(
sub foo () { #`(Sub|140681338496168) ... }
Data::Pretty gives you nice default stringifications for arrays, parcels,
hashes, and subroutines.
> use Data::Pretty
> [1, 2, 3] # brackets :)
[1, 2, 3]
> (1, 2, 3) # parens :)
(1, 2, 3)
> [1, 2, [3, 4]] # nesting :)
[1, 2, [3, 4]]
> /abc/ # yep, a regex :)
<regex>
> sub foo {} # short and sweet :)
&foo
I wish Perl 6 itself would implement this kind of stringification of data
structures, making this module obsolete.
