@section Unsafe C macros

All of the C functions & macros described previously verify that their
arguments have the appropriate types and lie in the appropriate ranges.
The following macros are identical to their safe counterparts, except
that the unsafe variants, by contrast, do @emph{not} verify coherency
of their arguments.  They are provided for the purpose of writing more
efficient code; their general use is not recommended.
