Subject: Sharing variables across methods

When writing short scripts (several pages long) I often want to share 
some variables (like CGI object, DB connection object) in several 
methods. I often use globals for this:

  $cgi = CGI.new('html3')
  $conn = PGconn.connect(...)

  def foo
    $conn.exec(...)
    $cgi.out { ... }
  end

When I don't want to see all those dollar signs, I use a wrapper method:

  $_cgi = CGI.new('html3')
  def cgi; $_cgi end

  def foo
    cgi.out { ... }
  end

But it still looks ugly to me. Any suggestion to make it more elegant?
