Add built in support for inline arrays

[archietse]

Maybe something like this:

{myObject}
key: value
arrayKey: value1, value2, value3
{}

We would need to devise a syntax for indicating the the "arrayKey" is not a normal key-value pair, but a list of items separated by commas.

Does it need to be inline? It would be more consistent to treat arrays inside properties as bulleted lists:

{myObject}
key: value
arrayKey:
* value1
* value2
* value3
{}
