C++ implementation of Lua?

["David Holz" <davidh@...>]

Just wondering if there is a C++ implementation of Lua anywhere.  With as
much as the lua_State pointers are passed around, it would seem to be faster
using the 'this' pointer, but more importantly it would be easier to
interface new C++ classes into Lua.

I really like Lua's interpreter code being as small, readable, and editable
as it is.  Having a C++ version would just make it that much easier for my
specific project, so I'm just curious about it.
