=head2 method default

Defined as:

    method default returns ???  # what should be written here

Usage:

    Hash.default

Returns the default value of the invocant, i.e. the value which is returned 
when a non existing key is used to access an element in the C<Hash>.
Unless the C<Hash> is declared as having a default value by using the 
L<is default|/routine/is default> trait the method returns the type object C<(Any)>.

    my %h1 = 'apples' => 3, 'oranges' => 7;
    say %h1.default;                                       # (Any)
    say %h1{'bananas'};                                    # (Any)

    my %h2 is default(1) = 'apples' => 3, 'oranges' => 7;
    say %h2.default;                                       # 1
    say %h2{'apples'} + %h2{'bananas'};                    # 4
