22.10.3 [func.def] defines

> -6- A call wrapper is an object of a call wrapper type.

Most importantly, a call wrapper is an object.

A number of functions in 22.10 [function.objects] and expressions in 26.5.7.3 [range.utility.conv.adaptors] and 26.7.2 [range.adaptor.object] are specified to result in a call wrapper. Most notably, the return type of `ranges::to` is `auto`, so its result is definitely a prvalue and not a "call wrapper" object.

Where a prvalue result is meant, the wording should be clarified to mean "a prvalue whose object it initializes is a call wrapper".
