I've come to take issue with the specification of Size.  It says it is
convertible to an integral type, does it does not say which.  I
believe the wording should be more precise -- yes, a library could
conservatively take long (long) or unsigned long (long), but still
that is a waste.  
Would you mind appending that issue to the one you raised in
c++std-lib-16112?
