The fatarrow, =>, is no longer just a quoting comma; it now constructs a Pair object. But you can still define a hash with an ordinary list of even length.
my %h1 = key1 =>'val1', 'key-2'=> 2, three => -238.83, 4 =>'val3';my %h2 = 'key1', 'val1', 'key-2', 2, 'three', -238.83, 4, 'val3';# Creating a hash from two lists using a metaoperator.my @a = 1..5;my @b = 'a'..'e';my %h = @a Z=> @b;# Hash elements and hash slices now use the same sigil as the whole hash. This is construed as a feature.# Curly braces no longer auto-quote, but Raku's qw (shortcut < ... >) now auto-subscripts.say %h1{'key1'};say %h1<key1>;%h1<key1> = 'val1';%h1<key1 three> = 'val1', -238.83;# Special syntax is no longer necessary to access a hash stored in a scalar.my $h = {key1 =>'val1', 'key-2'=> 2, three => -238.83, 4 =>'val3'};say $h<key1>;# Keys are of type Str or Int by default. The type of the key can be provided.my %hash{Any}; # same as %hash{*}class C {};my %cash{C};%cash{C.new} = 1;
