  Here are some other options:

	function() ... endfunction
	if ... then ... endif
	while ... do ... endwhile
	for ... do ... endfor
	do ... enddo -- hmm ... 

Okay ...

	function() ... noitcnuf
	if ... then ... fi
	while ... do ... elihw
	for ... do ... rof
	do ... od --- hmm ...

  The do keyword is problematic.  Several constructs use it, but it can be
used on its own to intruduce a new lexical scope.

  In my own code, I don't think I've ever used a semicolon.
