From 2662376941367d88687b3ebc4e4b941b266cee42 Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Mon, 22 Aug 2022 23:20:50 +0300 Subject: feat(tvix/eval): carry optional SyntaxNode in error type This starts paving the way for nicer, source-code based error reporting. Right now the code paths in the VM do not emit annotated errors, as we do not yet preserve that structure from the compiler. However, error emitting code paths in the compiler have been amended to include known nodes.
