I don't like multiple exits much myself, but something occurred
to me...

An if-then-else statement can have multiple returns:

	if a = 1 then
		...
	elseif a = 2 then
		...
	elseif a = 3 then
		...
	end

Each "elseif" is an exit from this block of code, as is the "end".

How does this figure into the se/se picture?
