Why for ORM Date is even an object? In most databases, date is a basic value type, and should be accepted by value, not as a complex object. So, it should also be identified as the value - for number 1, you do not need additional identity or hash except it being number 1, same should be for dates. > I don't believe (at all) in "if you don't need it mutable, don't use > modify() oroverride modify()".

Why it doesn't work well and why PHP needs to be changed because of it? -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
