13385	"Docs for for_each() should be clearer about forbidding ""any non-constant operation"""	Tony Lewis <tonyelewis@…>	Neil Groves	"The docs for Range's (single-range) `for_each()` function specify the requirement:

> !UnaryFunction does not apply any non-constant operation through its argument.

I think this wording could it be clearer. Does it mean that the it mustn't modify the value passed to it? If not, I think it would benefit from rewording. If so, isn't that quite different to `std::for_each()`. If that's deliberate, I suggest it's worth a brief note highlighting and justifying the difference. Otherwise, I suggest it's worth fixing.

Thanks very much."	Bugs	new	To Be Determined	range	Boost 1.66.0	Problem		range,for_each,docs,requirements,const
