I suppose it's linked to D's automatic initialization of variables. If I 
understand it correctly, just typing

   const int foo;

is the same as

   const int foo = 0;

With your suggestion, const variables could not be automatically 
initialized. In that case:

   int* foo;	   // foo is null
   const int* bar;  // bar could point anywhere!
