Scope parameter no longer works with Grid content

[mikemartin]

Bug Description

I'm in the process of migrating V2 site where I scoped grid content a lot, but when I use the scope parameter on grid content in V3, it throws a must be of the type array error.

How to Reproduce

Grid content:

grid:
  -
    text: test
    text2: test
  -
    text: test
    text2: test

Tag:

{{ grid scope="row" }}
  <h3 class="h3">{{ text }}</h3>
{{ /grid }}

Might be related. Also experiencing an issue with using the length modifier on grid content.

<div class="grid grid-{{ products|length }}up">
  {{ products }}...{{ /products }}
</div>

Error:

Method Illuminate\Support\Collection::__toString() must return a string value

[mikemartin]

@jasonvarga It seems like the solution here is that I no longer need to scope but if I really need to I can use a foreach.
Is that right?

V3 (should work like magic):

{{ grid }}
  <h3 class="h3">{{ summary }}</h3>
{{ /grid }}

V3 (if you must scope):

{{ foreach:grid as="row" }}
  <h3 class="h3">{{ row:summary }}</h3>
{{ /foreach:grid }}
