You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: raise_error.rb
    path of file: ./repos/ferrocarril/spec-runner/spec/mspec/lib/mspec/matchers
    
    the code of the file until where you have to start completion: class RaiseErrorMatcher
  def initialize(exception, message, &block)
    @exception = exception
    @message = message
    @block = block
    @actu
    
  def matches?(proc)
    @result = proc.call
    return false
  rescue Exception => actual
    @actual = actual
    if matching_exception?(actual)
      # The block has its own expectations and will throw an exception if it fails
      @block[actual] if @block

      return true
    else
      raise actual
    end
