Thanks a lot for your feedback!<br>
<br>
I have also intended to try finalization using a closure!<br>
But I wasn't that sure if it is an "idomatic" way to do that<br>
or there maybe an even more clever way for accomplishing it.<br>
<br>
<br>
By further googling yesterday I have also found similar <br>
code fragments at <br>

I'm just wondering about "cffi:finalize" which I couldn't <br>
find in my own installation of cffi package!<br>
<br>
Am I missing something?<br>

Using a finalizer seems to be a possible way to go. But I'm not sure how
this can be done by just using the finalizer parameters "object" and
"function"
where "function" can't reliablely access "object" (cf. documentation of
finalizer
in "trivial-garbage" package)!!

Here's some pseudo-code to achieve what you're looking for:
(let ((ptr (grab-your-table-pointer)))
(tg:finalize your-wrapper-object
(lambda ()
(table-free ptr))))
HTH,
