I think one trick is to do this:

  hello()

  BEGIN {
    def hello
      puts "Hi!"
    end
  }

but I'm not sure :)

I almost always code in classes, which tends to avoid this problem:

  class Example
    def initialize
      hello
    end

    def hello
      puts "Hi!"
    end
  end

  Example.new             # -> Hi!
