Pass view to function

[ChrisRackauckas]

Now, I want a function that I could call as
bar(view(foos, 3:4))
or as
bar(view(foos, [2,4]))
or as
bar(view(foos, :)).
What is the best way to achieve that?

function bar(x)
  # x is the view
end

This auto-specializes on the type so there’s no performance left behind here.
