Subject: Wrapping ENV

I just wrote a little piece of code. Is it useful to anyone but 
me? And/or do you see a more elegant way to do it, or any problems
with it?

I get tired of writing:

  ENV["this"] = x
  y = ENV["that"]

I'd rather write:

  env.this = x
  y = env.that

(Saving me brackets, quotes, and shift key.)

Here's the code:

  module EnvWrap
    ENV.to_hash.each do |name,value|
      newname = name.dup.downcase
      define_method(newname) { ENV[name] }
      define_method(newname+"=") {|val| ENV[name] = val}
    end
  end
  
  env = Object.new.extend EnvWrap
  
  p env.path
  env.path = "wocka"
  p env.path
  
  p ENV['PATH']


Cheers,
Hal
