I have a question about types. I have a `pulumi.StringArrayOutput` that I'm exporting through `ctx.Export`. When I'm importing this through `StackReference.GetOutput` in another stack I'm getting an `pulumi.AnyOutput`. How do I convert it? Should I use `.ApplyStringArray` in some way?

```AnyOutput.ApplyStringArray(func(value pulumi.StringArrayOutput) pulumi.StringArrayOutput {
   return value
})```
Result in a panic with a stacktrace

yes the conversion will be a little more involved:
```
output.ApplyStringArray(func(v []interface{})([]string, error) {
var result []string
for _, s := range v {
result = append(result, v.(string)
}
return result, nil
})```

May require a little tweaking. The signature might need to be `func(v interface{})` with an additional type assertion in there.

This ended up working for me:
```.ApplyStringArray(func(v interface{}) ([]string, error) {
	v2 := v.([]interface{})
	var result []string
	for _, s := range v2 {
		result = append(result, s.(string))
	}
	return result, nil
})```

I'm having most of my struggles with these custom pulumi types, once you learn how they're supposed to work it becomes easier to build the configurations, I think a lot of my struggles could've been solved if there were more practical examples. Some feedback for improving the docs.

Agree, we hope to improve the docs in this area.
