I am really not anything close to a fanboy of Oracle, but from what I read their new Graal VM sounds very interesting, as it removes most of the marshalling typically found in multi-language setups. Seems to me that their integration level is half step closer to the metal - but that might have been clever marketing blurb, as I have not researched in earnest.

Integrating the basic runtimes and mappable data types sounds better than the need for Ironpython and Jython sources to be changed for each new Python version. Having Node.Js accessible sounds also better than Rhino and Nashorn and always having to check what is supported. You were able to host Java runtimes as well (probably still possible), but going through JNI was/is a PITA

>Another good reason to look at .NET possibly more so than other languages is that you can at least interop with it from FoxPro. You can create a library in .NET and then call that from FoxPro either via COM Interop or via wwDotnetBridge to give you a big chunk of functionality that would otherwise not be available in FoxPro.
