It seems to be conventional to use the homoiconicity of Tcl to serialize data out in a way intended to be interpreted back in again as code [0], but I don’t think I’ve seen this recommended by Lispers.

> Parsing Prolog terms is easy. Parsing JSON correctly is very difficult: http://seriot.ch/parsing_json.php http://seriot.ch/parsing_json.php Most of that page is about character escaping as well as Unicode and floating point corner cases. You'll need to handle the same corner cases if you want to write a robust Prolog parser (it's slightly simpler if you cheat by rejecting Unicode).
