It may push several values to stack top, e.g.
lua_pushvalues(L, 5); /* copy top 5 values to stack top */

or it can accept 3 arguments and make lua_pushvalue as a macro to
lua_pushvalues? but I worry if that, It may difficult used in daily
tasks.

Now we have multiple delete (lua_settop), multiple move/replace
(lua_rotate), but multiple pushes is lacked.

Oh! I see, sorry for that.

It's can be used to perform IEEE tricks or others on some known
platforms (I can do this in my personal builded version :)
