It is possible to register finalizers, although they may only execute when the GC actually discards the objects, thus it cannot execute predictably (see http://ecls.sourceforge.net/new-manual/ch28s05.html). If you need more performance and predictability, you may want to provide some WITH-* style macros internally using UNWIND-PROTECT as well -- Matt ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Ecls-list mailing list Ecls-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ecls-list
