Perhaps it's just the patterns that I use when programming, but it's very
rare that I need a multilevel break in any other language that I use.  I
can't imagine that I'll ever want it in Lua.  

You can still break out of multiple loops--it just looks ugly:

local broken = false
while true do
  while true do
    if Test() then
      broken = true
      break
    end
  end

  if broken then
    break
  end
end

By the way, I'm VERY glad that breaks have made it into Lua!  Thanks!
