It seems you overlooked the fact that it is not implementable in current
Ruby, for it needs Procs to be rebound :)
 
It'd be easy to change it to specify the cleanup method, should it run
at all.

def auto(hash)
...
end

and then
  
auto( :a => :finalize, :file => close ) do
 file = File.new("/tmp/bla")
 a  = Something.new
end
