             ------------------------
 
-                Currently the only stable way to create a `Box` is via the `Box::new` method.
+
-                Also it is not possible in stable Rust to destructure a `Box` in a match
+            These are imported as if they were FFI functions, with the special
-                pattern. The unstable `box` keyword can be used to create a `Box`. An example
+            `rust-intrinsic` ABI. For example, if one was in a freestanding
-                usage would be:
+            context, but wished to be able to `transmute` between types, and
+            perform efficient pointer arithmetic, one would import those functions
+            via a declaration like
 
             ```rust
-                #![feature(box_syntax)]
