Hi, there

Is there any way to make YAML alias same strings in dumps? The following co=
de fragment:

require 'yaml'
s =3D 'a' * 10
puts [ s, s ].to_yaml

Produces this:
---
- aaaaaaaaaa
- aaaaaaaaaa

While I need:
---
- &id001 aaaaaaaaaa
- *id001

Interestingly, if I define s as:
s =3D [  'a' * 10 ]

The output is aliased just fine:
---
- &id001
  - aaaaaaaaaa
- *id001

Thanks,
Gennady.
