07:15 AM Ruby Bug #21654: Set#new calls extra methods compared to previous versions

I understand your point, but I personally disagree.
My concern is that the expectation to "if it's at all possible to raise early" is a slippery slope with no clear boundary.
For example, an operation like `(1..1<<100).to_a` will a... mame (Yusuke Endoh)

Yes. The original issue (#21513) was about the consistency between `(1..).to_a` and `(1..).to_set`. Since... mame (Yusuke Endoh)

>　How about handling only `Range` and `Enumerator` (not `Enumerable`) for now?
I think it would be better to handle only Range for now, and not Enumerator either. See https://bugs.ruby-lang.org/issues/21513#note-10 mame (Yusuke Endoh)

01:52 AM Ruby Bug #21513 (Open): Converting endless range to set hangs

The fix introduced another inconsistency:
```
$ ruby -e 'Enumerator.new(Float::INFINITY) {|g| loop { g << 1 } }.to_set'
-e:1:in 'Enumerable#to_set': cannot initialize Set from an object with infinite size (ArgumentError)

09:29 AM Ruby Feature #21650 (Feedback): Performance regression: Rational#floor(ndigits) extremely slow for huge ndigits in Ruby 3.4 (ok in 3.2)

Thank you for your reply.
I found a clearer case:
```ruby
p Rational(1, 3).floor(2**1) #=> (33/100)
p Rational(1, 3).floor(2**2) #=> (3333/10000)
p Rational(1, 3).floor(2**3) #=> (33333333/100000000)

Thank you for the report.
As the warning indicates, prior to Ruby 3.4 (up to 3.3), attempting to generate a huge `Integer` would return `Float::INFINITY`. Ruby 3.4 removed this inaccurate truncation, which is why it now takes longer. (#... mame (Yusuke Endoh)

Thank you, I'll close this for now. If there's anything else you'd like to discuss, please let me know. mame (Yusuke Endoh)

03:35 AM Ruby Feature #21642: Introduce `IO::ConnectionResetError` and `IO::BrokenPipeError` as standardized IO-level exceptions.

I talked with @akr-san. He said it should be first confirmed whether you have any real use cases that actually want to handle situations like "can't read but can write" (or vice versa).
Pipes are typically unidirectional, so when a wr... mame (Yusuke Endoh)
