> my conclusion was drawn from the following languages having their main compiler written in that language: Haskell, Java, Scala, OCaml, Kotlin, C++, C#, F#, Rust, Go, Nim, Zig... I don't see a problem, all those languages seem well suited to implementing a compiler. For comparison, the Bash scripting language would be a nightmare. > Most of these compilers were rewrites after a bootstrap implementation was created in an existing language. Sure, how else would they do it?

> Sure, how else would they do it? Write the very first version of the compiler for language X in X. Then hand-translate that compiler source to some other language or assembly. Then you don't ever have to rewrite the compiler.
