D is the scripting language. The whole benefit of D for the company I work for is that we only have one language.

Sil is distinct from d, and has distinct goals.

If we did SIL in C++ there's a good chance it'd have something like the UE4 header preprocessor to deal with all the hooks/metaprogramming we were able to D directly in D.
