I don't think I *really* need my microwave oven, or my automobile,
but I find them convenient tools to have around at certain times.

"Djikstra considered harmful"

I don't think Lua *really* needs 'repeat' and 'if'.  After all,
'while' should be sufficient for doing everything these other
keywords do.  However, I sometimes find it convenient to use one
or the other, depending on what the task at hand is.

There are actually a small handful of algorithms where the code
actually does look cleaner with a 'goto' than it would with
other constructs.  Most languages have some kind of construct
for unconditional, non-returning branches.
