in reply to Pugs Tic Tac

I'm pretty sure this won't run on Pugs, but it does have more Perl6ish features. 
use v6;

sub print_board ( @b ) {
    my $count = 0;
    for (@b) -> $x {
        print "$x \t";
        print "\n" unless ++count % 3;
    }
}

my @g = ('.') xx 9;

print_board( @g );

my %player = ('X','Player 1','O','Player 2');

my %entered;
my $choice = any (1 .. 9);

my $player = 'X';
while (@g ==> grep { $_ eq '.' })
{
    INPUT: {
        say %player{$player} ," Enter the Position [1-9]:";
        my $in = =$IN;

        unless ($in == $choice) {
            say "Please enter a value within 1-9";  
            redo INPUT;  
        }

        my $idx = $in - 1;
        if (%entered.exists($idx)) {
            say "Element already entered at $in";
            redo INPUT;
        }

        @g[$idx] = $player;
        %entered{$idx} ++;
    }

    for  (
        [ 0, 1, 2 ], [ 3, 4, 5 ], [ 6, 7, 8 ],
        [ 0, 3, 6 ], [ 1, 4, 7 ], [ 2, 5, 8 ],
        [ 0, 4, 8 ], [ 2, 4, 6 ],
      ) -> @c
    {
        if ( @g[@c[0]] eq @g[@c[1]] eq @g[@c[2]] )
            say "  %player{$player} Wins \n";
            exit;
        }
    }

    print_board( @g );
    $player = $player eq 'X' ?? 'O' :: 'X';

    I refactored your refactor to work in Pugs. It's a little hackish in parts, but it does work :)

    I committed it to svn http://svn.openfoundry.org/pugs/examples/games/tic_tac_toe.p6 and added some POD so as to give credit where credit is due. 

    #!/usr/bin/pugs

use v6;

sub print_board ( @b ) {
    my $count = 0;
    for (@b) -> $x {
        print "$x\t";
        print "\n" unless ++$count % 3;
    }
}

my @g = ('.') xx 9;

print_board( @g );

my %player = ('X','Player 1','O','Player 2');

my %entered;
my $choice = any (1 .. 9);

my $player = 'X';
while (grep { $_ eq '.' } @g) {
    
    say %player{$player} ~ " Enter the Position [1-9]:";
    my $in = =$IN;

    unless ($in == $choice) {
        say "Please enter a value within 1-9";   
    }
    else {
        my $idx = $in - 1;
        if (%entered.exists($idx)) {
            say "Element already entered at $in";
        }
        else {
            @g[$idx] = $player;
            %entered{$idx}++;

            for (
                [ 0, 1, 2 ], [ 3, 4, 5 ], 
                [ 6, 7, 8 ], [ 0, 3, 6 ], 
                [ 1, 4, 7 ], [ 2, 5, 8 ], 
                [ 0, 4, 8 ], [ 2, 4, 6 ]
            ) -> $c {
                if (@g[$c[0]] ne '.' && @g[$c[0]] eq @g[$c[1]] eq @g[$
+c[2]]) {
                    print_board( @g );
                    say "  " ~ %player{$player} ~ " Wins \n";
                    exit();
                }
            }

            print_board( @g );
            $player = $player eq 'X' ?? 'O' :: 'X';
        }
    }
