It has several applications, of which using it as a clipboard Lua table
by C routines is but one.However, if C is not involved at all, it is
not necessary to use it.

You can access it from Lua via the debug library. It's just a Lua
table that you can traverse with 'pairs' like any other. There are
some interesting things in it.
