def class_emitter_method?(node, name)

the method has the same name as a class defined in the class/module.
A class emitter method is a singleton method in a class/module, where 
def class_emitter_method?(node, name)
  return false unless node.parent && node.defs_type?
  # a class emitter method may be defined inside `def self.included`,
  # `def self.extended`, etc.
  node = node.parent while node.parent.defs_type?
  node.parent.each_child_node(:class).any? do |c|
    c.loc.name.is?(name.to_s)
  end
