PEAR_ExceptionBroker::create('BOOM', -1, PEAR_Exception::DB) would throw a DB_Exception if the class exists, or did I misunderstand you? :) > In addition to the categories, there are some Exception features that > would be very nice, for example: > > - NestableException Right, very well! > How does one propose code that goes into core PEAR?
