06:26 AM Ruby Bug #21780: Change the default size of Enumerator.produce back to infinity

> However, the change that made Enumerator#to_set refuse to operate when the size returns infinity introduced a compatibility issue
TBH, I don't see the compatibility argument applied with any consistency here.

04:40 PM Ruby Bug #21784: Proc#source_location start column seems strange for -> {}

I too, would expect the whole expression to be covered. This would be also consistent with `Method#source_location` which includes `def` (and not starts from the argument, or from the beginning of the body). zverok (Victor Shepelev)

07:17 PM Ruby Bug #21780: Change the default size of Enumerator.produce back to infinity

There are, by the way, other effects of the current default that are, even if minor, still annoying:
```ruby
Enumerator.produce(1, &:succ).lazy.take(6).size
# Ruby 3.4: => 6 -- which is correct and useful
# Ruby 4.0: => nil -- ... zverok (Victor Shepelev)

10:19 AM Ruby Bug #21780: Change the default size of Enumerator.produce back to infinity

I would argue that it is _known_ to be infinite: that's how `produce` works: loops infinitely, unless explicitly stopped by an _exception_, t... zverok (Victor Shepelev)

08:46 AM Ruby Bug #21780 (Open): Change the default size of Enumerator.produce back to infinity

In #21701 a new argument `size:` was introduced, and its default value is `nil` (unknown).
While I support the new argument, I'd argue that the default should be `Float::INFINITY`.
**Reasoning:** By _design_, `Enumerator.produce` ... zverok (Victor Shepelev)

@jeremyevans0 Thank you for the clarification. I'll try to consider adjusting the docs to reflect the design. zverok (Victor Shepelev)

08:50 AM Ruby Misc #21777: DevMeeting-2026-01-14

* [Bug #21780] Change the default size of `Enumerator.produce` back to infinity (zverok)
* While the new argument is a good addition to the API, I argue that `Float::INFINITY` would be a more friendly default, corresponding to the mos... zverok (Victor Shepelev)

06:31 PM Ruby Feature #21389 (Open): Simplify Set#inspect output

Just noticed that on the latest `master` subclasses `#inspect` didn't change (unlike what @matz suggests here: https://bugs.ruby-lang.org/issues/21389#note-3):
```ruby
class MySet < Set

p Set[1, 2, 3] #=> Set[1, 2, 3]

06:11 PM Ruby Bug #21778 (Rejected): Binding#eval vs implicit parameters

This works:
```ruby
proc { |x| binding.eval('x') }.call(1) #=> 1
```
This doesn't (neither with numbered parameters, nor with `it`):
```ruby
proc { _1; binding.eval('_1') }.call(1) # undefined local variable or method '_1' for ... zverok (Victor Shepelev)
