	Somehow, my impression was that it /does/ allow for nested
	variable scopes.  However, I have only a passing experience with
	the language.

	I disagree.  I deem the use of nested scopes as crucial to code
	structuring.  Should the "roles" of the variables (whether
	input, output, or local) become apparent later, it'd be trivial
	to split the function, -- and that's likely to be done exactly
	along the scope boundaries previously coded in.
