How to easy set size of multi dimentional dynamic array?
for example:
class Foo{
  private double[][] m_array;
  this(uint o_length, uint o_width){
    // hard way:
    this.m_data.length = o_length;
    for(uint i = 0; i < this.m_array.length; i++){
      this.m_array[i] = new double[o_width];
    }
  }
}
