RB_RESERVED_WORDS

MethodNameChecker::RB_RESERVED_WORDS is the list of reserved words in Ruby that take an argument. Unlike VariableNameChecker::RB_RESERVED_WORDS, these reserved words require an argument, and a NoMethodError is raised due to the presence of the argument.

The MethodNameChecker will use this list to suggest a reversed word if a NoMethodError is raised and found closest matches.

Also see VariableNameChecker::RB_RESERVED_WORDS.
