I think that may have been the case.

However, often the situation doesn't really arise in Ruby, as blocks
are used for these kind of purposes. I've personally switched over to
a style where 99% of resource management is done using blocks, and it
really does make life simpler:

   DB.connect(name, pw) do |db|

       # .. do lots of database stuff

   end
