Who said they are?  In your example the double quotes aren't necessary,
but they are required if you want to be able to interpolate that variable
in a more complex string:

print "User name = $username\n";

Of course you could also do

print "User name = ", $username, "\n";

or

print "User name = " . $username . "\n";

I'm lazy and hate typing all of those commas and dots. :-)
