Cannot use `[x, .. n]` in statics

[huonw]

rusti> static A: [uint, .. 3] = [0, .. 3];
rusti> A
<anon>:9:32: 9:39 error: constant contains unimplemented expression type
<anon>:9         static A: [uint, ..3] = [0,..3];
                                         ^~~~~~~

I guess this is mostly relevant to static mut.
