I had this problem too.
I think these three solutions are obvious:

1. Protect the 'require' like in C:
test.rb:
if loaded == 0
  loaded=1
  bla bla bla
  whatever that was in test.rb
  bla bla bla
end

2. Use forward declaration
test.rb:
class Code end
Code.something()

3. Refactor so that 'test' uses the interface of 'code'.

Personally, I like solution #2 because it's easy and fast. I put all
the forward declarations in a separate file which is 'require'd by
both code.rb and test.rb.
