I skipped an interesting part of Mnicolet's message. But I think it
raise the following issue: is lua a C or C++ embeddable scripting
language, i.e. does the Lua API target C or C++?

I definitely think Lua (even the 5. and future 6. versions) should
target C, not C++.

If you designed a language easy to embed into C++ applications (which
lua is not, it targets C not C++) you'll get a different API and a
different language.

I undestand C++ coders are using Lua, but Lua should target C coders,
not C++ one!
