The REPL decides whether it has a complete statement to execute by doing
a load() on whatever it has, and seeing if there's a syntax error at the
very end of the input. So in your example, the first two calls to
block() are for the strings [[do]] (which fails) and [[do print("Lua")]]
(which also fails), and then the third call for [[do print("Lua") end]]
succeeds and the REPL then runs the resulting chunk.
