shoud dotview be documented?

[oxinabox]

I found that to make x[:, y=2] .= 7 to work,
I needed to overload Base.dotview for my array type.
(see invenia/NamedDims.jl#1)

Which is not documented on the broadcasting docs page.
It does have a non-docstring comment above it, that mostly explained things.

It shouldn't be something you need to override. I think its base implementation should just forward any kwargs to view/getindex by default, which would solve your problem.

That said, it is something that gets generated by lowering, and it is exported from Broadcast, so it'd be good to document.
