Thanks, Corentin.

Let's say Resolution=MOVED, since nothing got fixed in GCC.

Thanks; seen fixed with

"[Clang] Use of decltype(capture) in parameter-declaration-clause".

Agreed, clang should implement the proposed resolution to CWG2569 very soon so
there isn't anything that needs to change in libstdc++

Clang implements the wording correctly:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2036r3.html#pnum_3

So int a = 0; [a] (decltype(a)) { }; is ill-formed now. But I'm not convinced
that's a good change to make as a DR.

This code isn't valid pre-C++11 so we can just use decltype, not __decltype.
