+The value of statics and constants must be known at compile time, and they live
+for the entire lifetime of a program. Creating a boxed value allocates memory on
+the heap at runtime, and therefore cannot be done at compile time.
+
+Erroneous code example:
+
+```compile_fail,E0010
+#![feature(box_syntax)]
+
+const CON : Box<i32> = box 0;
+```
