I meant that dropping constness:
char ch = '='; // OK
results in an error:
lambda.cpp: In lambda function:
lambda.cpp:4:23: error: ‘ch’ is not captured
4 | [](auto) { return ch; }; // OK

The warning is not sensitive to what is being switched on. That is the inner
most switch is considered as falling through as the switch is not checked for
the values it will be switched on.

On the original code (I can attach it if needed, but it is large, it is
resizing a std::vector with reference-counted elements) FRE3 fails to simplify

Another use case is C++20 atomic_ref, which may be bound to an object whose
padding bits are in indeterminate state. An intrinsic to clear padding bits
without altering the object value could be usefu

Without the constructor, we get plain
*this_2(D).a = {};
which is expanded as an __int128 store. With the constructor, we get
MEM[(struct M *)this_2(D)].p = 0B;
MEM[(struct M *)this_2(D)].sz = 0;

This should have a test-case added, ideally by renaming an already existing
