Don't clobber your caller's variables.. so.. in .. 
sub a {
 @_;
 $_;
}

$_ is .. what of the caller?

And am I to understand that in sub a, messing with @_, regardless if the caller passed any references as arguments, is potentially messing with the caller's arguments?

(thank you for your patience here)
