Most programming difficulties might come from having an incomplete knowledge base or not having the right tools to work with.

You might need XEmacs that points you all the ({[ pairs for easy visualizing them. There are also other editors that do the same. But XEmacs, once you get used to it looks very much more an expert in perl than oneself :) .

By using -w at the starting line: 

#!/use/bin/perl -w
##and followed by 
use strict;

Might help a lot. But remember that you might need to add some more conditionals to your sentences:

if (($location) && exists($list{$location})) {
    my $value = $list{$location};
    $value++;

    $list{$location} = $value if ($value);

...for example, just to illustrate the use of verified existing variables.

But then, the error messages are very descriptive and easy to track down.
