One of the reasons I came to D is because I can feed and read 
data from openGL using pointers rather than having to duplicate 
(Marshal) data from the stack to the managed heap before I can 
interact with openGL (C#). It is redundant to be reading vertex 
attribute data from a file into managed memory when the 
destination of that data is the graphics card. It is better to be 
reading the file data into a stack based struct, handing the 
pointer to this data to the vbo, securing the vao id and then 
dropping the stack at function exit. If for no other reason it 
reduces the work required by the garbage collector continuously 
reorganizing the heap as vertex data transits through it.
