Quick question on post grammar.

Hi!

I have been seeing stuff like this a lot:

```

they’re not afraid of getting a rudimentary 1.0 out into the world.

```

I am confused about some things. What is the plan for handling nested blocks? I think ending a block with a matching `` would work better? For instance:

```

```

Could be ambiguous as to where the block begins and ends. By using `` and ``, you would get rid of that potential confusion. Is the goal to have every block be represented on its own throughout the HTML? I am not a parsing expert so there is probably something I am overlooking.

No source file, test, or entry point is named. Start by reading the nested-block examples and the repository's grammar and parser work, then determine how block boundaries should be represented and how the decision can be verified for nested text and image blocks.
