>I have some reservation about using two interpreter-based languages in a single application. Application deployment could possibly become quite complex. I like simple dev environments such as an interpreter-based language à la fox or python calls to dlls or fll(vfp) for external parties.

I can follow your reasoning ;-)

But newer attempts might make such ideas more palatable:

- Graal VM aims to use identical "entities" as basic program data structures, so no marshalling between different VMs is needed and a common runtime for different interpreter languages can be utilized.
- WASM aims for more interdependency with JS, offering for instance lonnger integer types, probably via typed arrays

correct. You need COM exe for GUI, but the mechanics should work. But nothing I would consider future-proof ;-)
