That is the only way to do it in D1 AFAIK. In D2 you have 
__traits(compile, ).

But before you get into discussion, please read my point made to Walter: 
  possibility to get such a functionality is not and SHOULD NOT be 
connected with template instantiations, but rather with proper compile 
time reflection.
