Perl 6 Deep Dive

Increment and decrement operators ++ and --

These are the prefix operators to increment and decrement the value.

Prefix forms of these operators first change the value of the variable and then return the result.

my $n = 42;++$n;say $n;   # 43say --$n; # 42

In Perl 6, both ++ and -- operators have the form of postfix operators (see examples in the Postfix operators section later in this chapter).
