This should be a compiler error or at the very least issue a 
warning.

It seems to me that overridden sub-struct opAssign needs to be 
chained together, and it's a compiler error if there's a break in 
the chain, i.e., if a sub-level struct has non-default opAssign, 
then the parent must have one too, else it's an error.
