+//   Persistence of floating-point types
+
+//   Note: despite years and years of IEEE standardisation, not all
+//   architectures use IEEE-standard representations of floating-point numbers.
+//   Therefore a binary dump is not necessarily portable between platforms.
+//   Solving this is (currently) beyond the scope of the STLplus project.
+
+//   If you want to be strictly portable to all platforms, do not dump/restore float
