c++: lambda capturing structured bindings [PR85889]
<https://wg21.link/p1381r1> clarifies that it's OK to capture structured
bindings.
[expr.prim.lambda.capture]/4 says "The identifier in a simple-capture shall
denote a local entity" and [basic.pre]/3: "An entity is a [...] structured
binding".
It doesn't appear that this was made a DR, so, strictly speaking, we
should have a -Wc++20-extensions warning, like clang++.
PR c++/85889
gcc/cp/ChangeLog:
* lambda.cc (add_capture): Add a pedwarn for capturing structured
bindings.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/decomp3.C: Use -Wno-c++20-extensions.
* g++.dg/cpp1z/decomp60.C: New test.
