/*
	(name,value) pairs are useful in many contexts. This is just the first and simplest variant.
	Exercise 6.4 is another variant.

	Note how we could read a (name,value) pair and used a specific name to indicated the end of input.
	There is a second (undocumented) way of terminating the input. Try leaving out an integer; for example,
		frank 3 joe bill 7
	You may consider that a bug or a feature. If you consider it a bug, you'll find it a bit hard to detect
	it reliably.

	Checking for duplicates is another common activity, and easy.
