Isn't the ability to do that one of the biggest reasons for having
namespaces? To avoid having to fill your class names with junk.
The examples are namespaced appropriately, they tell the developer that it's
a Helper for Arrays in the MyFramework framework. I shouldn't need to suffix
the class name with 'Helper' to reconfirm that, just because the PHP engine
doesn't like it.
This thread really should be re-titled to "allow reserved words as a classname or not". Then perhaps the only logical response to the question would be so obvious that there would be no thread... oo-er...
