	And I'll second that...

	In those languages that use "then" as a keyword, it separates the "if"
conditional from the "true" block of code. Or -- visualize replacing the
":" on the "for" with the word "then"

	for x in sequence then
		do stuff with x
	else
		do something with no x


	If a different keyword is to be introduced, I nominate "otherwise"
