Hi,

Thank you! Getting the number of arguments first seems to be great.
Though it seems a bit odd to allow top to bottom indexing with a non-empty stack only, while the bottom to top method works in both cases... It's a bit inconsistent, but it's probably just me.

Hi,

Is this meant to work with a -1 stack index (i.e. from top to bottom)?
Because whenever I use lua_isstring or lua_isnoneornil with -1 it seems to
be broken. If I attempt to check the stack using 1, it works fine.



Like Mike mentioned earlier, this is not an acceptable index
http://www.lua.org/manual/5.1/manual.html#3.2

You should check the stack height with lua_gettop to check the number
of arguments passed to a function.

Cheers,
Josh.
