Hello,

I would like to accomplish the following:

float[3][4] vertices = [ [1.0, 1.0, 0.0], [-1.0, 1.0, 0.0], [-1.0, -1.0, 0.0],
[1.0, -1.0, 0.0] ];

This does not work, errors about static initializers with nonstatic types.
Great, so vathix tells me to do:

const float[3][4] _vertices_init = [ [1.0, 1.0, 0.0], [-1.0, 1.0, 0.0], [-1.0,
-1.0, 0.0], [1.0, -1.0, 0.0] ];
float[3][4] vertices = _vertices_init;

This does not work.  Setting it to .dup does not work, slicing it does not work.
The errors are cannot convert float[3][4] to float.  


This is silly, why can't we use an initializer with a non-static types?!
