Constructing a serialised YAML string in Ruby

Sometimes you want to convert a YAML document to an encoded format that can then i.e. be base64-encoded, or stored in another form.

I fought against this the other day and it took me a bit of work to work out that we can write the following CLI Ruby incantation to give us what we need:

ruby -ryaml -e 'p YAML.load(' < a.yml
# outputs:
# "---\ninfo:\n  version: 1.2.3\n"
