It was/is one of the defining points of D AFAIK.
More than being theoretical it chose to be pragmatic, to solve the  
problems we face day to day.
For the case at hand; Say uninitialized variables in C are undefined but  
all the compilers do
the same thing that makes it in practice defined. So the below line should  
execute same on all compilers.

	type a;

Same applies to the extensions supported in all major compilers which is  
absent in language spec.
If compilers don't support, they can't sell.

To the point. If you want to keep B-D rule with the presence of such big  
design mistakes (C), you are not being pragmatic at all.
