Hi everyone,
Last Friday Triplequote published a report [1] about the state of Scala compilation in 2018. The analyzed data was obtained thanks to over 600 individuals that have taken the time to share their experience with Scala. While the dataset is not large, it does provide some insight on how much time is lost by Scala developers every day because of compilation.
