[Accepted at the February, 2022 meeting.]
The changes of P1787R6 inadvertently made constructs like
if (int a = 1) if (int a = 1) ...
ill-formed.
Proposed resolution (September, 2021):
Change 6.4.3 [basic.scope.block] bullet 2.2 as follows:
If a declaration whose target scope is the block scope S of a
compound-statement of a lambda-expression, function-body, or function-try-block,
substatement of a selection or iteration statement that is not itself a selection or iteration statement, or
handler of a function-try-block
potentially conflicts with a declaration whose target scope is the parent scope of S, the program is ill-formed.
