I noticed that in some places in Phobos range-related code, there's an assumption that the following code works:

	auto someRangeFunction(R)(R range) {
		...
		R helperRange = range;
		...
		helperRange = R.init;
		assert(helperRange.empty);
		...
	}

Exercise for the reader: spot the bug.

Hint: what if R is an InputRangeObject?
