These deduction guides are provided for to allow deduction from:

1) A container and a comparator.
2) A container and an allocator.
3) A container, a comparator and an allocator.
4) The std::sorted_unique_t tag, a container and a comparator.
5) The std::sorted_unique_t tag, a container and an allocator.
6) The std::sorted_unique_t tag, a container, a comparator and an allocator.
7) An iterator range and a comparator.
8) The std::sorted_unique_t tag, an iterator range and a comparator.
9) The std::from_range_t tag, an input_range range, a comparator and an allocator.
10) The std::from_range_t tag, an input_range range and an allocator.
11) The std::initializer_list and a comparator.
12) The std::sorted_unique_t tag, the std::initializer_list and a comparator.

These overloads participate in overload resolution only if InputIt satisfies
LegacyInputIterator, Alloc satisfies Allocator, and Comp does not satisfy Allocator.

Note: the extent to which the library determines that a type does not satisfy
LegacyInputIterator is unspecified, except that as a minimum integral types do not
qualify as input iterators. Likewise, the extent to which it determines that a type
does not satisfy Allocator is unspecified, except that as a minimum the member type
Alloc::value_type must exist and the expression
std::declval<Alloc&>().allocate(std::size_t{}) must be well-formed when treated as
an unevaluated operand.
