Yes. As I mentioned in my original post, I tried "newindex",
"__newindex", as well as "index" and "__index". My function is never
called.

So I don't lose the context, here is the important bits of my original
post are below. Maybe this isn't as easy as I thought it would be.

My 4.0 code looked like this:

  lua_pushcfunction(L, getglobal);
  lua_settagmethod(L, LUA_TNIL, "getglobal");

For 5.0 I tried to do this:

  lua_pushvalue(L, LUA_GLOBALSINDEX);
  lua_getmetatable(L, -1);
  lua_pushstring(L, "__newindex");
  lua_pushcfunction(L, getglobal);
  lua_settable(L, -3)

But my function never gets called. I also tried "index", "__newindex",
and "__index", but no avail.

FYI, what I am trying to do is catch statements of the form:

  package.name = "MyPackage"

...where `package` hasn't been defined yet. My function will create a
table, populate a few values, and then setglobal("package") before
returning.
