Experiment on exception and `retry` of Ruby: what scope does the `retry` call effect? Answer is the method that invokes `retry_me`.

retry_me_and_exception_me.rb

def retry_me(&block)
    begin
        yield
    rescue
        retry
    end
end

def say_hi
    retry_me do
        puts "hi"
        raise "runrunrun!!"
    end
end

say_hi
