Numbers as YAML keys broken?

Numbers as YAML keys broken?

[BP Jonsson]

(I'm resending this as it seems it didn't get through.)

It seems like pandoc 2.2.2.1 thinks that a metadata block with 
numbers as
mapping keys is a table. If I quote the keys/numbers it seems to 
work OK.
Is this really as it's supposed to be? AFAIK the YAML 1.2 spec doesn't
mention any such restriction.

Please see the three example inputs and outputs below.
The second one displays the problem.

/bpj

```
IN
---
foo: bar
baz:
   biz: buz
---

Quux.
OUT
<p>Quux.</p>
IN
---
0: bar
1:
   2: buz
---

Quux.
OUT
<table>
<tbody>
<tr class="odd">
<td>0: bar</td>
</tr>
<tr class="even">
<td>1:</td>
</tr>
<tr class="odd">
<td>2: buz</td>
</tr>
</tbody>
</table>
<p>Quux.</p>
IN
---
'0': bar
'1':
   '2': buz
---

Quux.
OUT
<p>Quux.</p>
```

We switched to a pure Haskell YAML parser that
implements YAML 1.2, and a few things are different.
I noted in the release notes some changes in booleans,
and this appears to be another example. Just quoting
the numbers will work:

---
'0': bar
---

The HsYAML author says that there are some settings in
HsYAML that we could fiddle with to make this quoting
unnecessary. I need to look into this. If you want,
you can submit something on the issue tracker.

Just pushed d3d932f42cd361a7b4d7e2b22a3238f53cb54f6b
which should fix this and allow unquoted numbers as
YAML keys.
