Re: Lua 5.4.2 New assorted suggestions (Part II)

 For literal strings, lua_pushstring is both simpler to use and faster. 

lua_pushstring(L, "cannot close standard file");

Can be simpler, but it is not faster than:

/* avoid strlen call or inline */

lua_pushlstring(L, "cannot close standard file", sizeof("cannot close standard file") - 1);

    Compilers nowadays won't call strlen for string literals:

Don't assume, test, measure, look at the compiler's output.
