I apologize, I misunderstood your statement. I get what you mean now,
but it's mostly a moot point. The starting point is completely
arbitrary, and fact of the matter is it's possible to construct a
concatenation operation that takes an extremely long time. Point is, Lua
operators are not necessarily fast and negligible operations.
