From a2b4b4a48521d1751fa9c88cec980f0b4b59427d Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Wed, 10 Aug 2022 18:00:04 +0300 Subject: fix(tvix/value): implement PartialOrd/PartialEq for strings Instead of comparing the enum variants (which does not yield useful behaviour), compare &str representations of the string instead.
