Is it possible to instantiate *vectors* of models in MTK?

What I mean is the following. I have created a re-usable “class” which I have named `Well`

. In the past, I have instantiated several copies of this model and used the instances in equations, example:

```
@mtkmodel Field begin
# Components used
@components begin
...
w1 = Well()
w2 = Well()
...
end
# Equations for connecting components
@equations begin
w1.p_i ~ ...
w2.p_i ~ ...
...
x ~ w1.p_i + w2.p_i + ...
end
end
```

This works. However, with many instances of `Well`

, the code is ugly.

What I would like to do is something similar to:

```
@mtkmodel Field begin
# Components used
@components begin
...
w[1:5] = Well()
...
end
# Equations for connecting components
@equations begin
w[1:5].p_i .~ ...
...
x ~ sum(w[1:5].p_i)
end
end
```

When I do this, and try to build the model:

```
@mtkbuild f = Field()
```

I get an error message:

```
type Array has no field p_i
```

**Question**:

- Is it
*possible*to use arrays to instantiate models? - If yes, how do I need to modify my code?
