US296 24.07.11.3 Converting constructor for split_view::outer_iterator is slightly wrong #292
Description
split_view::outer_iterator converting constructor is slightly wrong. In split_view::outer_iterator<V, Pattern>, when V is not const-iterable, we must avoid forming the type iterator_t since it will fail to compile.
Proposed change:
For the converting constructor:
constexpr outer_iterator(outer_iterator<!Const> i) requires Const && ConvertibleTo<iterator_t<V>, iterator_t<const V>>;
change the requirement to:
requires Const && ConvertibleTo<iterator_t<V>, iterator_t<Base>>;
