Re: a tentative design of a finalization mechanism for Guile

[Carl R. Witty]

If people are doing research on finalization mechanisms for Guile, I'd
recommend reading:

 Stretching the storage manager: weak pointers and stable names in Haskell
 (http://www.research.microsoft.com/Users/simonpj/Papers/weak.ps.gz)

They come up with mechanisms for finalization and weak pointers which
they claim are preferable to guardians.  (Although the paper describes
Haskell, the mechanisms -- particularly in sections 5 and 6 -- are
easy to apply to other languages.)
