You just can't introduce type safety to a scripting language without 
modifying the VM implementation, you may search if there is some fork of 
the library doing that.

In DQuick we expose D object to the Lua VM by using the Lua C library.
Its API allow us to expose D structures or classes directly.

If the API of the VM of your scripting language is written in C, it's 
almost the same as if you write a C++ application.
