Is there any advantage or disadvantage to setting this attribute (memory
consumption, performance, etc.)?  If you have getter/setter functions for a
property, is there any reason that you *shouldn't* set this attribute?

I didn't know about this attribute as it's not documented at:

I need to browse here more often. :-)
