    The border function is already beautifully documented, but not named,

    particular cannot be called by that metamethod. It would be nice to
    have it exposed, and `table.border` seems like a natural place for it.
    To achieve that while conforming to the custom that the libraries use
    only lualib.h and lauxlib.h, one would need `int lua_border(lua_State
    *L, int index)`.

What about 'rawlen' and the C function 'lua_rawlen'? They ignore the __len metamethod.


What about a table.border that respects __index?
