But a template/abstract class could at least be used to share code and remove
duplication. Adding the data members can be done by inheritance or something?

The duchain is fast afaik, last time I profiled the slow part was the disk-
access. And since in PHP you don't have #include's you can follow, you have to
load every single file of the probably hundreds of files in your project (esp.
with frameworks that have one class per file).

- "is class with static members" (since in PHP, Classes don't act as
namespaces you don't have to show them during global code completion, when
they don't have static functions/constants etc. pp.)
- "is exception class" - there are a few special cases where you only require
a list of classes that inherit from the Exception class, otherwise you'd have
to iterate over every class and check that yourself
- "pretty identifier" (see case insensitivity etc.)
Maybe more, niko is out to get something to eat :)
