I believe that this is the kind of clever, evil stuff the OP was trying to avoid...
(evil - eval :-) - besides eval is very slow - not something you (well me then) want to
use in a function dedicated to object creation which is comparatively slow anyway
(try comparing the speed of cloning and creating objects in php5 for instance
regardless - nice one for posting this Eli - I recommend anyone who doesn't understand
what he wrote to go and figure it out, good learning material :-)
