RB_RESERVED_WORDS

VariableNameChecker::RB_RESERVED_WORDS is the list of all reserved words in Ruby. They could be declared like methods are, and a typo would cause Ruby to raise a NameError because of the way they are declared.

The :VariableNameChecker will use this list to suggest a reversed word if a NameError is raised and found closest matches, excluding:

* +do+
* +if+
* +in+
* +or+

Also see MethodNameChecker::RB_RESERVED_WORDS.
