This week, I wrote some code that made me wish we already had support
for structured bindings and return by initializer list (both from
C++17) for mozilla::Tuple.
That is, if we have
mozilla::Tuple<size_t, size_t> Foo()
it would be nice to be able to call it via
auto [a, b] = Foo();
and within Foo to write returns as
return { a, b };
It appears that our minimum GCC and minimum clang documented at
https://developer.mozilla.org/en-US/docs/Mozilla/Using_CXX_in_Mozilla_code
are pretty old.
What's the current outlook for increasing the minimum GCC and clang
versions such that we could start using structured bindings and return
by initializer list for tuples (either by making sure mozilla::Tuple
support these or by migrating from mozilla::Tuple to std::tuple) and
thereby get ergonomic multiple return values in C++?
