Here is my problem:
I have a hash (it's 4 dimensional, but we'll only use a 2 dimensional hash for the question! :-) containing key value pairs.
%food_color = ("Apple" => "red", "Banana" => "yellow");

[download]
When I'm updating a value, I need to be case insensitive on the key side, so that: 
%food_color = ("APPLE" => "blue");

[download]
replaces "Apple" => "red"

I have looked high and low, 3 O'Rielly PERL books and every online reference I could find. Nothing even addresses the idea. Has anyone had to do this? Is it possible? Or did I just waste an hour looking for a solution?

Your humble servant,
-Chuck
