SClass represents a block of statements that should be evaluated within the context of the singleton class of an object. It’s frequently used to define singleton methods.

class << self
end

Node

the target of the singleton class to enter

  @target = target
  @bodystmt = bodystmt
  @location = location
  @comments = []
end

def ===(other)
  other.is_a?(SClass) && target === other.target &&
    bodystmt === other.bodystmt
end
