  And that wouldn't work.  I'd say "What was I thinking?" but I actually
know what I was thinking when I wrote the above.  

  I initially started to reply by stating one could just as easily use the
__concat metamethod (assuming one had been assigned to complexLValue):

	complexLValue .. newElement

but I realized that wouldn't work, it would have to be:

	complexLValue = complexLValue .. newElement --[1]

which takes us to the proposal under consideration, and I ended up with

	complexLValue = @[#@ + 1] = newElement

which wouldn't work even *if* Lua had this feature.
