After reading that a couple of times it is a bit clearer, thank
you. I need to wrap my head around this. I am working on a simple
render/game engine, where, of course, vectors and matrices are
flying around.
Is the compiler sophisticated enough that is it able to avoid the
copying. For instance, if i have a struct Matrix4x4 a =
node.getTransformation() and use a for whatever, but never alter
it, will it be able to avoid the copy? What if i declare it const
or immutable? Do i have to use a pointer to it?
After doing some small stuff in D I am not impressed by the
mental mapping I am having with the memory system currently. I
have some more experience with high performance programs in C++
and appreciate the transparency of the memory management.
