Re: Is there something like a lua_trypushstring() with return value? Could there be?

No, lua_pushcfunction (as opposed to lua_pushcclosure with a non-zero n)
cannot raise a memory error. See the manual:

    lua_pushcclosure
    
    void lua_pushcclosure (lua_State *L, lua_CFunction fn, int n);
    [...]
     When n is zero, this function creates a light C function, which is
     just a pointer to the C function. In that case, it never raises a
     memory error.
