I've been messing with my "Japh" thing (I tried to space it out for this node as best I could) and I noticed something peculiar (to me, at least):
V(qw/74 401 211 79/);
sub V{while(@_){
$v**=$V?$#_:$V;
print(
    map{
        $V<$v?
            chr(shift):
                chr(reverse(pop))}$_)
        ,$V+=$#_%2!=1?1:0}}

If I swap the while for a for, it only prints out "Ja".
Why might it do that?
I thought I may be cutting it off early by pop'ing off of the end, but that doesn't make any sense to me.

Thanks in advanced! 



V(qw/74 401 211 79/);sub V{while(@_){$v**=$V?$#_:$V;
print(map{$V<$v?chr(shift):chr(reverse(pop))}$_),$V+=$#_%2!=1?1:0}}
