Hi Monkees

The following one liner prints, rather unexpectedly, 'still defined' - any ideas as to what's going on?

perl -e "$x[0]=[0];map{undef $_}(@x);print 'still defined' if defined 
+@x;"

map{$a=1-$_/10;map{$d=$a;$e=$b=$_/20-2;map{($d,$e)=(2*$d*$e+$a,$e**2
-$d**2+$b);$c=$d**2+$e**2>4?$d=8:_}1..50;print$c}0..59;print$/}0..20
