Hi, The Reference Manual documents a number of procedures for handling object properties based on association lists (https://www.gnu.org/software/guile/manual/html_node/Object-Properties.html). However it says: “this is a legacy interface; you should use weak hash tables or object properties instead“. Does that mean that support for this kind of object properties will be removed in the future? In my opinion the suggested alternatives aren't nearly as handy as the so-called legacy interface.
Cheers.
