[ChangeLog][QtCore][QFuture] Introduce
QtFuture::makeReadyRangeFuture(). This method takes a container
which has input iterators and returns a multi-value
QFuture<ValueType>, where ValueType is the underlying type of
the input container.
This commit also replaces the usage of buggy
QtFuture::makeReadyFuture(const QList<T> &) overload with the new
method.

QMultiHash has access to two sizes: one of them is shared with QHash,
stored in QHashPrivate::Data::size, which counts keys; the other, which
is what our public size() function returns, is stored in
QMultiHash::m_size and counts plain (key,value) entries. We forgot to

Currently, Qt assumes that enums always have int as their underlying
type (both in QMetaEnum::keyToValue and in the QML engine). This change
makes it possible to to retrieve the underlying type from an enum's
metaype - or rather, a metatype of an integral type with the same size
and signedness. The use cases aobve don't really rely on the exact same
type. In most cases, we wouldn't even need the signedness, however that
is already available anyway, and it will come in handy once QML supports
bigint, and we need to decide whether we should return
While it would be possible for individual users of this function to
manually query the size and signedness, having a function returning a
metatype offers additional convenience - especially in QML, where the
conversion APIs generally operate on metatypes.

well as to allow generic code to treat QVariant and std::variant the

the same as get_if<T> != nullptr. The index-based variant access
functions (get<I>()/get_if<I>()) are also not provided, because,

alternative types, and QMetaType IDs are not (all) compile-time

QVariant supports non-default-constructible payloads, in principle
(QTBUG-105140). And fromValue() works with such types, but value()
insists on providing a wide contract and therefore accidentally
requires default-constructible.
We can now invent other "Qt-ish" API like optional::value_or() or a
value() that returns optional<T>, but we should first get the
interface in that generic code must use, and which at the same time is
the most versatile, because it gives write access to the element
stored in the variant: [variant.get], consisting of get_if(), get(),
and holds_alternative(). The latter is the same as get_if() !=
nullptr, so we won't provide it.
This first patch implements get_if(), adds test for it.

arguments, we run into the problem that wg21.link/P0846 solved for

In C++17, unqualified lookup doesn't find function templates that

P0846, merged for C++20, fixes this to repeat the name lookup, parsing
the < as indicating a template.

work for the purpose of Structured Bindings, but don't work for manual
unqualified calls when P0846 semantics are missing, and we're adding
