Functions
		getweakrefcount(...) getweakrefcount(object) -- return the number of weak references to 'object'. getweakrefs(...) getweakrefs(object) -- return a list of all weak reference objects that point to 'object'. proxy(...) proxy(object[, callback]) -- create a proxy object that weakly references 'object'.  'callback', if given, is called with a reference to the proxy when it is about to be finalized. ref(...) new(object[, callback]) -- create a weak reference to 'object'; when 'object' is finalized, 'callback' will be called and passed a reference to 'object'.
