From 6ecfe643b5d8d64682c6f6bce5b27db5c007331d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=89tienne=20Barri=C3=A9?= Date: Mon, 24 Mar 2025 12:17:58 +0100 Subject: Freeze $/ and make it ractor safe [Feature #21109] By always freezing when setting the global rb_rs variable, we can ensure it is not modified and can be accessed from a ractor. We're also making sure it's an instance of String and does not have any instance variables. Of course, if $/ is changed at runtime, it may cause surprising behavior but doing so is deprecated already anyway.
