Hi! Thanks for providing the timeline.

However, the docs have is_subclass_of() documented as accepting string while is_a() is not and it worked as always returning false given non-object. I think we could easily keep this behavior for 5.3 even though I think relying on this is wrong (and you SHOULD fix it anywhere your code relies on it, including PEAR). -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
