Charles,

What you try point is not very correct. IMHO.

IT will be correct IF constructor do automatic open().
But it not do this.

Technique which you describe is very common for C++ developers.
    constructor do some action
    destructor do its alternative.

I will not explain advantages of this technique.
They are described in the "C++ PL" of Stroustrup.

MAY BE btw, this technique can be useful for RB developers!
I think 100% can be used. Than more that now RB have exceptions..
