#
#	Demonstrate the use of lvalue scope.  lvalue scope may be applied
#	to individual procedural arguments or to the return value.  It
#	causes the caller to pass the object by reference instead of by
#	value, allowing the procedure to modify the contents of the
#	object.
#
#	This feature is most often used when implementing operators that
#	require lvalues, such as "++" and "&=", but it can be used to
#	great effect with normal procedures as well.
