Hi,
I have the following code snippet :
        void    set()
        {
                GLfloat[]       data = [
                        -1.0f, -1.0f, 0.0f,
                        1.0f, -1.0f, 0.0f,
                        0.0f,  1.0f, 0.0f,
                ];

                glBindVertexArray(mVAO);
		glBufferData(GL_ARRAY_BUFFER, data.sizeof, cast(void*)data, 
GL_STATIC_DRAW);
        }


And I ask my self about the memory management of data, as my 
data array is statically initialized is it allocated on stack?

Note that if you can define the data array as immutable, you save 
on heap memory allocation + copying (LDC, from -O0):
