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

[Kais Ben Salah via RT]

For further providing you with informations about how to reproduce this NYI 
bug, I've attached a perl script, that you can test perl6 with.

#!/usr/bin/perl6

my $i = 0;

itr:
$i++;
goto itr if ($i < 10);

say $i; #shall output 10
