So after looking into it a little bit...

It looks like the opAssigns can take all the attributes without 
throwing errors so that's good.

The postblit can only not take @nogc due to the array duplication 
which is understandable.
I think the postblit might be redundant anyway since the struct 
is built on a static array so there is no possibility of two 
different Vect3s "pointing" to the same data.
Can someone confirm or does the postblit do anything else?
