before at -> already initialized at ?

I'm not sure I understand this. Won't it just say:

"field foo is initialized more than once (before at foo)"

I would think there should be a diagnostic for each "duplicated" initializer.

Removed 'before at' in favor of a second warning.

No, it would print the initializer node. I removed it and print another warning
now.
