__Traits functions are evaluated at compile time so it's not as 
simple.
The best you can do is to generate a string to mixin based on the 
aggragate members. here i have an example of how you can iterate 
through the members:

Writing an opAssign() operator will be as fast, you just need to 
remember to keep it in sync with the classe members.

You could also generate the struct programmatically, based on the 
classes declaration.
