The thing about languages is that you can write other languages inside them. You can implement garbage collection in C. You can compile it to Java bytecode. You can convert Java bytecode to x86 assembly. You can write your own preprocessor to allow C++ style templates in Go. You can make a shim that will allow you to make calls to the Go networking library from a shell script.
The question is not whether you can do something, it's how many hoops the language makes you jump through to do it.
