## Parable: Comments in Variables

Variables in Parable now require a stack comment.

This has lead to a few important changes:

- anything you create with **var**, **var!**, or **::** will have a comment in the first cell and a stored value in the second
- to use the **@** and **!** prefixes the initial comment is necessary
- you can no longer use **head** to access the stored value

I'm honestly a bit undecided on the usefulness of this. It'll be helpful when building the documentation, but may make some things a little more complex. For now I'm trying it out. It remains to be seen if this is something that'll stay in place or revert to the previous model (where variables do not have any embedded comments).
