# There is no special handling needed to copy a string.
{
    my $original = 'Hello.';
    my $copy = $original;
    say $copy;            # prints "Hello."
    $copy = 'Goodbye.';
    say $copy;            # prints "Goodbye."
    say $original;        # prints "Hello."
}

# You can also bind a new variable to an existing one so that each refers
# to, and can modify the same string.
{
    my $original = 'Hello.';
    my $bound := $original;
    say $bound;           # prints "Hello."
    $bound = 'Goodbye.';
    say $bound;           # prints "Goodbye."
    say $original;        # prints "Goodbye."
