From 5ad1915bbc6a9aec6d1795532a554a5d6c2ed283 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 25 Oct 2018 12:10:50 -0600 Subject: [PATCH] Give names to tuple fields This gives numeric names to tuple fields, because lldb clients expect fields to have names, and because using plain numbers seemed most rust-like.
