Local by default used to confuse me no end in Python.  If Lua used it then:

do
  a = 1
  do
    a = 2  -- is this a new local or the same as the one above?  How do I tell Lua whether I want it to be the same or different?
  end
  print(a) -- does this print 1 or 2?
end

I much prefer global by default - it seems do be defined better.
