Thanks! And correct... at the moment, the system browser can't be used
to write code in different languages. We've tried out some ideas that
involve compilerClass, but we haven't found a good way to integrate
GraalVM languages nicely yet. As you know, most languages are
file-based and don't have built-in support for persistence, so there
are some interesting problems to tackle. If you have any ideas in that
direction, please let us know!
