The "range" clause in a "for-range" loop now accepts iterator functions of the following types

	func(func() bool)
	func(func(K) bool)
	func(func(K, V) bool)

as range expressions.
Calls of the iterator argument function produce the iteration values for the "for-range" loop.
For details see the [language spec](/ref/spec#For_statements).
