  It doesn't seem right to me that until has access to the inner scope of
the loop; isn't that violating the scope or something like that?  

  Also, is the issue with coninue this?

	repeat
	  code()
	  if blah then contiue end
	  local i
	  more_code()
	until i

  Or with this?

	repeat
	  local i
	  code()
	  if blah then continue end
	  more_code()
	until i

  Or both?  I'm not sure what the problem is.  In C, a continue in a "do ...
while" skips the conditional test.  Is the issue the conditional test?  Or
the creation of the locally scoped variable?
