What's the reason you're not doing:
$obj = new EmailAddress('[email protected]');
or
$obj = new Money('16.99', new MoneyType('USD'));
... actually, email is the only one of the above mentioned classes, that
could have just one value (neither zip code nor money make sense without
context, as zip codes and money depend on locale). That's an aside though.
Main question being: are you arguing for operator overloading in PHP when
you should just use better constructors?
