are three ways to declare formal parameters to a closure.
- $func = sub ($a, $b) { print if $a eq $b }; # standard sub declaration
- $func = -> $a, $b { print if $a eq $b }; # a "pointy" block
- $func = { print if $^a eq $^b } # placeholder arguments

A bare closure without placeholder arguments that uses C<$_>
(either explicitly or implicitly) is treated as though C<$_> were a
formal parameter:
- $func = { print if $_ }; # Same as: $func = -> $_ { print if $_ };
+ $func = { .print if $_ }; # Same as: $func = -> $_ { .print if $_ };
$func("printme");
In any case, all formal parameters are the equivalent of C<my> variables

There is no C<foreach> statement any more. It's always spelled C<for>
in PerlĀ 6, so it always takes a list as an argument:
- for @foo { print }
+ for @foo { .print }
As mentioned earlier, the loop variable is named by passing a parameter
to the closure:
