Go is a compiled statically typed programming language famous for its implementation of CSP.
- Example of a Tcl extension in Go
- Gotcl - a not quite a full "reimplementation" of Tcl as a Go library.
- gothic - Tcl/Tk Go bindings.
- libmill is a lightweight coroutine library bringing Go-style concurrency to the C language. Not directly related to Tcl but possibly of interest if someone wants to write a wrapper. Note that unlike Go, which does M:N threading, libmill is single-threaded.
