And the reason I chose <> is that in Perl 6 qw// is will be replaced
by the diamond operator*. Also, when accessing a hash with a bareword
(or set of barewords in the case of a slice) you say
%hash<foo> = "bar";
rather than
$hash{foo} = "bar";
When using a string or a variable you still use {} like this
%hash{$key} = "bar";
%hash{'foo'} = "bar";
One upshot of this is that it is much easier to write this Perl 5 code
my %start; @start{qw<month day year>} = split /\//, shift;
as
my %start<month day year> = split /\//, shift;
There is a similar operator named <<>> (or if you prefer unicode «»)
that acts as an interpolating qw//. So you can say
my $key = "foo";
my %hash<<$key bar baz>> = 1, 2, 3;
and wind up with three keys: foo, bar, and baz.
* the old diamond operator will be replaced by unary = and operates on
all iterators, not just file and directory handles.
