They use a special protocol to make data access from different 
languages transparent and very low cost. Perhaps worth an experiment to 
see if D can benefit of it.

I think there's an option so that LLVM bitcode can be used on it. 
So conceivably, you could compile with LDC to LLVM bitcode and 
then run that on Graal.

Here is the documentation [1] for this feature. There is some 
discussion about linking standard libraries in Rust/C++ that 
might be relevant.

In case anyone wondered.

It works with betterC mode using dpp to translate polyglot.h.  I 
guess I need to build druntime and Phobos bitcode libraries.

A higher level wrapper around polyglot wouldn't be so much work.

One more thing.  This makes it pretty easy to compile Java 
libraries as native code libraries that you could link to from D. 
  Not everything will work because of reflection and dynamic class 
loading restrictions.  But being able to use Java libraries might 
be quite useful for D.

How can D benefit from JVM JIT Extension?
