for a quick lookup on var-contents i use to print it via print "\$var: $var\n"; Now i noticed that the value of hashes can't be printed in contrast to other var-types if the hash is enclosed in quotation marks. 
$s="1 x 2 y";
@a = $s;
%h = @a;

print "\$s: $s\n";
print "\@a: @a\n";
print "\%h: %h\n";

print "\%h: ", %h, "\n";

produces 
$s: 1 x 2 y
@a: 1 x 2 y
%h: %h
%h: 1 x 2 y

why that ?
