For arrays which are made via similar or are just distributed the same, this would be a really nice operation since then inplace operations can be used.

Yes. This should work. It might not be too difficult to mimic the out-of-place broadcast to get an in-place broadcast but with broadcast you never know. The corners can be quite tricky. I'll take a look.

[vchuravy]

Should be supported now
