09:03 AM Ruby Feature #21858: `Kernel#Hash` considers `to_h` too

I have no strong objection, but it is true that we have big side effect when we allow `to_h` from `Hash()` as @Dan0042 pointed out for example.
What do you think?

08:18 AM Ruby Feature #21871: Add Module#undef_const

First, it doesn't seem directly related to the example and the functionality being proposed. Second, it doesn't directly explain the pros and cons of introducing `undef`ining constants. At this point, I don't see the need for it.

08:13 AM Ruby Feature #21822: Expose Return Value in the ensure Block

I don't think it's not worth for the new syntax, where you can do similar thing with:
```
begin
ret = begin
# ....
end
ensure
LOGGER.debug "return value: #{ret}"
end
```

08:09 AM Ruby Feature #21813 (Rejected): Add [:forward, :...] symbol tuple to indicate forwarding arguments when calling `Method#parameters`

I failed to persuade me. I admit there's a lack of symmetry, but I don't think it's not worth the potential performance burden.

07:38 AM Ruby Bug #21808: Inconsistency in support of additional newlines with boolean logical operators on new line

I agreed with @nobu here. Fluent method calls (`.`) behave same.

07:13 AM Ruby Bug #21844: Inconsistent ArgumentError message for Data::define.new

OK, these are bugs (string keys, integer keys). We should fix.
