Define `Base._parentsmatch` for `AbstractVectorOfArray`

[bertini97]

Copying from a view to a view requires Base._parentsmatch(::TypeOfView1, ::TypeOfView2) I think for optimization reasons. RecursiveArrayTools currently doesn't define this.

Two solutions:

• RecursiveArrayTools defines

  Base._parentsmatch(::AbstractArray, ::AbstractVectorOfArray) = false

• Base defines

  Base._parentsmatch(::Any, ::Any) = false

It's weird that base doesn't define a default for this. They didn't think someone would extend views?

Does Base._parentsmatch(::AbstractArray, ::AbstractVectorOfArray) = false invalidate? If not that is probably the right thing to do, though it seems like it's supposed to be internal...

I don't know what invalidate means in this context. It works however, setting it allows me to continue. I agree internal should provide a default to false. Do I open an issue to Julia?

yes
