If you are going to port the garbage collector, then what is the 
point of changing object.d. Yes, each class comes with extra 
typeinfo which takes up space but if that's a big problem then 
you are in a microcontroller size class that is not suitable for 
D. Then betterC and C is a better choice. I'm thinking about 
something like systems with 512KB RAM/Flash and more, then is the 
extra type information that big of a problem? D is great as it 
allows dynamic RTTI (C++ term) by default and by removing 
typeinfo you will remove such functionality.

Systems that has 32KB of RAM and such, forget about D all 
together and use C (not even C++). BetterC might work though.

I haven't done any size comparison what you really save by 
removing the extra meta data. Do anyone really know how much it 
really is?
