+//!     overflow the pointer type of the process it describes a range in.
+//!
+//! This class checks bases of type `mach_vm_address_t` and sizes of type
+//! `mach_vm_address_t` against a process whose pointer type is either 32 or 64
+//! bits wide.
+//!
+//! Aside from varying the overall range on the basis of a process’ pointer type
+//! width, this class functions very similarly to CheckedRange.
