Course of Raku / Essentials / Code blocks

Local variables

What if you declare a variable not only in the global scope but also locally in the block?

my $x = 1;

{
    my $x = 42;
    say $x;
}

say $x;

The program has two independent variables now. They share the name, but all references to $x in the global scope are about the global variable, while the $x inside the block is a local variable, different from the global $x. The program prints two different values:

$ raku t.raku
42
1
