 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;
 ```
