lua -e "print(_VERSION)"
--> Lua 4.0

So _VERSION is already there; it's set in the baselib.

IMHO the bug is the calling convetion on tinsert itself.  The
statement

  tinsert(x, foo())

does completely different this when foo returns 1 or 2 results.
I think, these collection of functions would be better:

  tinsertat(table, pos, elements...) -- insert at pos
  tinsert(table, elements...)  -- insert at 1
  tappend(table, elements...)  -- append at -1
