Actually this can be seen in the two links

1. Cppinterop: https://compiler-research.org/CppInterOp/lab/index.html

2. xeus-cpp: https://compiler-research.github.io/xeus-cpp/lab/index.html

Try automatic printf (maybe type 10 and execute the shell )

it would error out for cppinterop but not for xeus-cpp (now an output is not expected cause its not yet implemented https://github.com/llvm/llvm-project/blob/73dd730fb9403ca648a46b489bf04e27b2a93840/clang/lib/Interpreter/Value.cpp#L258-L266 but whenever it would be we are ready to support it and this would be required.)

Can we add a test demonstrating this now works?

Can we add a test demonstrating this now works?

Well unfortunately this is one thing I am not well versed with :(

Never written any concrete "tests' as such for an emscripten use case and also I don't think any other xeus-lite kernels support testing right now.

I shall raise this point in front of xeus-lite maintainers today and see if there is something we can do !

We could add a unit test that uses this symbol and it will fail as part of the ci, right?
