Lisette — Rust syntax, Go runtime

Little language inspired by Rust that compiles to Go.

There are several languages that compile to Go, trying to be a better a Go. Off the top of my head: XGo (https://github.com/goplus), Borgo (https://github.com/borgo-lang/borgo), Soppo (https://github.com/halcyonnouveau/soppo)...
XGo

The XGo Programming Language. XGo has 102 repositories available. Follow their code on GitHub.

How do compile errors propagate back from the target language to the source language?
They are not supposed to produce code that doesn't compile, why would they?
