Understood! :-)  decltype is just around the corner though (imho, and 
from a practical standpoint), if not already here.  __typeof__ 
currently works for this purpose on both gcc and Metrowerks.  And rumor 
has it decltype (or at least __decltype__) isn't far behind.

<nod>  I believe we'd need to call the versions by different names.  
Walter Brown has suggested "extent" for the compile-time version of 
dimension.
