Error code E0010

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:

#![allow(unused)]
#![feature(box_syntax)]

fn main() {
const CON : Box<i32> = box 0;
}
