But as you noted, that will only work if your arguments are always true, or that false indicates "default value". The nice thing about using the %hash = ( default => "value", @_ ); construct (besides being shorter) is that it works for all values.

To do the same with explicit testing you'd need 

$args{arg1} = 'default value1' unless exists $args{arg1};
