AnomalousMonk it's correct what you say, but it only work with scalars, it doesn't work with more complex structures like hashes (or references to hashes):

EXAMPLE: 

 perl -wMstrict -le 'print qq{perl version: $] \n};;; my $x; my %y= ("
+h"=>1, "i"=>2);  print $x, $y{x}; printf "%s", $x;'

OUTPUT: 
perl version: 5.018002

Use of uninitialized value $x in print at -e line 1.
Use of uninitialized value in print at -e line 1.

Use of uninitialized value $x in printf at -e line 1.
