What are best practices for working with fat comma =>?

# Example of using the fat comma operator in Perl
use strict;
use warnings;

my %data = (
    name    => 'John Doe',
    age     => 30,
    email   => 'john.doe@example.com',
);

# Accessing values in the hash
print "Name: $data{name}\n";  # Output: Name: John Doe
print "Age: $data{age}\n";    # Output: Age: 30
print "Email: $data{email}\n"; # Output: Email: john.doe@example.com
