This should be brought up on Yaml-core.  (And has been before.)  The spec is 
conflicting on this matter.  Compare examples 2.21 and 2.24.

  >> YAML::load("{x: 73, y: 129}")
  => {'x' => 73, 'y' => 129}

Or should that be {'x' => 73, true => 129} ??  Too confusing.

They previously eliminated '+' and '-' on similar grounds.  Before that, you
could do:

  ---
  true: (y)
  false: (n)
  ---
  true: (+)
  false: (-)
