Fields are not all unique.
<input type="checkbox" name="ice_cream" value="chocolate"> Chocolate
<input type="checkbox" name="ice_cream" value="vanilla"> Vanilla
<input type="checkbox" name="ice_cream" value="strawberry"> Strawberry
If all three boxes are checked, the query string (or information coming on
STDIN) will include
ice_cream=chocolate&ice_cream=vanilla&ice_cream=strawberry
So code that does:
$form{$field} = $val;
is broken.
