Currently the value of _ is currently unspecified in this case.
Are you suggesting that _ be defined for any compound assignment
or just during a type definition?
If it is for every compound assignment, then what is the value
inside a nested assignment?

I hadn't even realized that this works. It works because the assignments
are done in order.

I have been thinking about using the name create in this case so that
if you define a function named create, it will be invoked when each
instance is created.
