FSE/CACM Rebuttal$^2$: Correcting A Large-Scale Study of Programming Languages and Code Quality in GitHubEmery D. Berger, Petr Maj, Olga Vitek et al.
Ray, Devanbu and Filkov issued a rebuttal of our TOPLAS paper "On the Impact of Programming Languages on Code Quality: A Reproduction Study". Our paper reproduced "A Large-Scale Study of Programming Languages and Code Quality in GitHub", which appeared at FSE 2014 and was subsequently republished as a CACM research highlight in 2017. This article is a rebuttal to that rebuttal.

Scala Implicits are Everywhere: A large-scale study of the use of Implicits in the wildFilip Křikava, Heather Miller, Jan Vitek
The Scala programming language offers two distinctive language features implicit parameters and implicit conversions, often referred together as implicits. Announced without fanfare in 2004, implicits have quickly grown to become a widely and pervasively used feature of the language. They provide a way to reduce the boilerplate code in Scala programs. They are also used to implement certain language features without having to modify the compiler. We report on a large-scale study of the use of implicits in the wild. For this, we analyzed 7,280 Scala projects hosted on GitHub, spanning over 8.1M call sites involving implicits and 370.7K implicit declarations across 18.7M lines of Scala code.
