[perl #131412] [NYI] Label.goto() not yet implemented

[Kais Ben Salah via RT]

The attached script below, is meant for a Perl5 goto support, works fine - 
which means that Perl6 has missed a feature from Perl5.

#!/usr/bin/perl

my $i = 0;

itr:
    $i++;
print "$i\n";
goto itr if ($i < 10);

print "$i\n"; #shall output 10
