gcc16-pr120776-wip.patch
Latest state.
Still need more testcases (though admittedly something will just not work until
P2686R4 is implemented fully), figure out what to do about range extension (see
https://github.com/cplusplus/CWG/issues/724 for some issues), whether using
ptrdiff_t(i) that the patch currently uses for iterating expansion statements
is ok (see https://github.com/cplusplus/CWG/issues/725 ) and at least add a
testcase for redeclarations (both something declared in init-stmt with
for-range-declaration and possibly (see
https://github.com/cplusplus/CWG/issues/729 ) also in the body. I think the
code currently does diagnose it even in the body, but will need testcases.
Also tests for tuple based structured bindings (both in destructuring expansion
statements and when structured bindings are used in for-range-declaration).
Also tests for what happens when it is not iterating and is not valid
destructuring either.
