I'm looking forward to when this exists for every almost language. Go added "c-archive" build mode in 1.5. There is no reason gobind couldn't support any language which can work with c libraries (ruby, node, etc).

This exists for Python [0]. The reverse is also interesting (Go -> Java/Python/Ruby) and once I get some spare time, I'll play around with using libjvm to load and call jar files from Go.

In case the author sees this, more documentation would be great.

Yup. I'll put together some more docs and usage examples this weekend.

Go would benefit immensely from the ability to bind to JDBC drivers for database access.

Its awesome. The problem is that only specific types are supported by a bunch of these types of libraries. In the case of gopy you cannot do anything with a nested slices in structs which limits things a bit.

What makes you think so? Go has pretty solid native drivers for most SQL databases out there: https://github.com/golang/go/wiki/SQLDrivers

Since GoJava generates jar binding, does it mean other JVM languages can use the jar to call Go too?

Edit: Java has generic Go doesn't, how do the bindings work for generic?
