constexpr explicit /*sentinel*/ ( /*zentinel*/ <Const> inner ) ;
(3) (exposition only*)

Constructs a sentinel.

1) Default constructor. Default-initializes the underlying sentinel object inner_
2) Conversion from /*sentinel*/<false> to /*sentinel*/<true>. Move constructs the underlying object inner_ with std::move(i.inner_)
3) Value-initializes the underlying object inner_ with inner

Parameters

i - a /*sentinel*/<false>
inner - an underlying object of type zentinel <Const>
