I always found this very useful - it meant that the compiler whinged at
if you got it wrong - it's useful for confirming where each structure
ends in your mind. Alas, I don't think this kind of thing is possible
to be implemented optionally in Lua, as it is in Basic, as the compiler
wouldn't be able to tell the difference between the end or a beginning
of a block. :-/
