Subject: Weak reference facility in Emacs.
Date: Wed, 22 Jan 2020 22:11:02 +0800 [thread overview]
Message-ID: <877e1jlgy1.wl-all_but_last@163.com> (raw)
Weak reference is good idea to deal with cycle reference. Though Emacs has GC,
but weak reference is also useful when I want to use RAII pattern in Emacs (via
finalizer).
hash table has option to make reference in it become weak. But it's not
so convenience if user just want a weak reference of *ONE* lisp object.
Would you interest in some lisp library to wrap a weak table to provide weak
referenece utils. Or it's better to implement it in alloc.c?
