    How do you test code that uses fat comma =>?

    The fat comma, also known as the fat arrow (=>), is a feature in Perl that is commonly used to associate keys with values in hash structures. It provides a cleaner and more readable way of defining key-value pairs compared to the traditional method of using commas and other syntax. Here’s a simple example to illustrate its usage:

    my %hash = ( 'key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', ); print $hash{'key1'}; # Output: value1
