Very true!  It being a rainy afternoon, I modified the parser to
accept anon functions as arguments. In the function funargs in
lparser.c, added another case:

    case TK_FUNCTION: { /* funcargs -> function */
       luaX_next(ls);
       body(ls, f, 0, ls->linenumber);
       break;
    }

Oops - ambiguity - it thinks this is an assignment! Not as easy as it looks.
