Subject: [ruby-talk:11901] Class Destructor?

I have a class where the initializer takes a filename
and opens a file. The class has several methods to let
the user get information from the file.

The problem is, I don't know how to have the class
close the file automatically like a destructor would 
in C++. (Maybe I have missed something big here)

I see 2 options:

1) Put the burden on the user with #begin #end

begin
  c = Myclass.new("file")
  c.meth1
  c.meth2

  ensure
    c.close
end


2) Or I could store the file pointer in the class and
have each method open the file, move to the proper location,
do its thing, save the file pointer, close the file.
But this seems kind of kludgy.


Any other ideas out there?

Thanks
