betterC and std.containers don't work together?

[Ki Rill]

I've been trying out std containers. Checked Phobos code - all 
seems to be @nogc. Good. Then I try out this and it fails because 
something throws in array construction and that's not available 
in betterC: https://run.dlang.io/is/WAjVuG

```D
extern(C):
import core.stdc.stdio;
import std.container;

void main()
{
     printf("hello, world\n");
     Array!int ai;
     ai ~= 1;
}
