I wish Perl would at least have an option to, during clean up, decrement the ref count on all globals, destroying things in the normal manner, and after that, would then go sweep up anything that was left over.

I think that this has been fixed, to some extent, in 5.7.2. The following is from the Changes file.

[ 7991] By: jhi on 2000/12/05 15:52:34 Log: Subject: Re: [PATCH] The largest hoax of all times? From: Ilya Zakharevich <ilya@math.ohio-state.edu> Date: Tue, 5 Dec 2000 00:40:25 -0500 Message-ID: <20001205004025.A4050@monk.mps.ohio-state.edu +> ... Fix the unpredictable order of DESTROYs. ...
The fix was also discussed in the p5p digest.

Nevertheless, on 5.7.2 I still have problems with Perl objects that contain sub-objects which are destroyed too early. However, I am not sure if this is part of the same problem.

    [choroba]: but undef %hash and %hash = () both work, too, but the first one keeps the memory allocated, while the latter makes it available for other parts of the program.
    [choroba]: iirc
    [perldigious]: karlgoethebier: Well it is a pretty old and complicated (for me) bit of code I wrote (poorly by my current standards), so I'm expecting everything to break when I add the scoping and find out what else is undesireably scope changed. :-)
    [perldigious]: Ah, thanks choroba, that sort of thing was precisely what I was wondering when I asked.
    [perldigious]: I didn't want to tie up memory unecessarily basically, I wanted to "delete" it specifically to free it up, and wasn't sure I was even accomplishing that.
    [stevieb]: perldigious You should start by writing some unit tests. That'll ensure current functionality doesn't break with changes.
