Your concerns seem ill-founded given that these are solved problems. There are working implementations of low-barrier cross-language compatibility, today, for both the JVM and the CLR. Here's one example; Rhino provides pretty seamless bridging from JavaScript to Java: https://developer.mozilla.org/en/Scripting_Java https://developer.mozilla.org/en/Scripting_Java I've used it to run user-supplied JS inside the JVM. PHP is pretty easy too: http://quercus.caucho.com/quercus-3.1/doc/quercus.xtp#JavaPHPintegration http://quercus.caucho.com/quercus-3.1/doc/quercus.xtp#JavaPH... Scala is even more lightweight here: http://www.codecommit.com/blog/java/interop-between-java-and-scala http://www.codecommit.com/blog/java/interop-between-java-and... Bear in mind that these are all for the JVM, which wasn't even designed with the intention of being a general-purpose multi-language VM.

I can't speak to the JVM, but I know for a fact that some CLR languages have incompatibilities (C# and F# specifically).

  Both directions. There are impedance mismatches, of course, but it's nothing like the doomsday scenario he's claiming.

> Your concerns seem ill-founded given that these are solved problems. Then solve the problem I put before you. It's an easy one. I want to pass a modified Date object with stored procedures that modify the value based on geolocation. I want to pass it from a Javascript function to PHP/Java/whatever. Make it work. Please.

  First of all, it's difficult to engage with your productively, as you're particularly confrontational. That said, if you give me some example code, I'll demonstrate its use in a JavaScript/Java hybrid implementation when I have some spare moments.
