Lua yield allows waiting for threads in Lua?

[FakeTruth]

I've hit a bit of a roadbump.. GCC does not seem to allow passing a template function as a template function's template argument (template template template)

For example this compiles fine in visual studio, but gives me an error in GCC

tolua_function(tolua_S, "ForEachPlayer",         tolua_YieldTemplate< tolua_ForEach<cWorld, cPlayer, &cWorld::ForEachPlayer> >);
