YAML: Keys like "yes" or "no" evaluate to true and false

If you parse this Yaml ...

yes: 'Totally' no: 'Nope'

... you get this Ruby hash:

{ true: 'Totally', false: 'Nope' }

In order to use the strings 'yes' and 'no' as keys, you need to wrap them with quotes:

'yes': 'Totally' 'no': 'Nope'

There's actually a long list of reserved words Archive with this behavior:

y|Y|yes|Yes|YES|n|N|no|No|NO |true|True|TRUE|false|False|FALSE |on|On|ON|off|Off|OFF

I'm sorry.

Does your version of Ruby on Rails still receive security updates?
