- 2020-11-10: 1 Regression, 2 Improvements, 2 mixed
A mixed week with improvements still outweighing regressions. Perhaps the biggest highlight was the move to compiling rustc crates with the initial-exec TLS model which results in fewer calls to
_tls_get_addr and thus faster compile times.
See the full report for more.
Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

This time we have two quotes of the week:
i just spent 8h finding a mutability bug and now i wanna be a catgirl
– @castle_vanity on twitter reacting to a post depicting C++ programmers as muscle-laden bodybuilders and Rust programmers as catgirls
Thanks to Maximilian Goisser for the suggestion.
The code people write is first a question to the compiler, and later a story for people changing that code.
llogiq is mightily pleased with his suggestion.
