Fil-C has a large performance impact though, and it'll always be reasonably significant. Rusts popularity has always been the combo of safety and performance, otherwise you might as well just use C#
Combined with the ability to compile to a single native binary, having a solid package management solution, a fairly advanced type system, and a solid selection of nice language features. Usually you need to give up at least one of those.
Good to see a praise for C#.
