a=5; // I get notified, Put() is called
a+=5; // nothing happens

Check out the code in opcodes.d under IRaddass:, that's what gets executed
for a +=. Either putVnumber() or putVstring() is called.

Adding this:

Dobject o_o=b.toObject();
if(o_o) o_o.Put(s,v,0);

after line 694 of opcodes.d seems to do the trick. I don't know if it is 
right to have zero for attributes and if it breaks something else but 
maybe time will tell (or Walter?). It is very nice because it could 
eliminate the need of setters/getters for certain functionality (like 
mywindow.setX() for example), which means less coding and less 
limitations, which is, I believe, cool. I don't know if it isn't against 
ECMA, but maybe it worths adding to the official distribution?
