05:00 AM Ruby Feature #21518: Statistical helpers to `Enumerable`

Hi. I'm a creator of enumerable-statistics gem and the original proposer of `Array#sum` and `Enumerable#sum`.
In general, adding only `mean` (I prefer `mean` over `average`, see below) and `median` won't cover real-world statistical nee... mrkn (Kenta Murata)

08:06 AM Ruby Feature #20705: Should "0.E-9" be a valid float value?

> But I think it's good to make Float/to_f to accept "0.e-9"
Changing `String#to_f` introduces incompatibility:
```
$ ruby -ve "p '1.e-9'.to_f"

09:05 AM Ruby Feature #20266: New syntax to escape embed strings in Regexp literal

I agree with this proposal. Even if Ruby enables `\Q` and `\E` features in Onigumo, they don't work as expected if the embedded string contains `\E`. Therefore, it would be better for Ruby to have a short syntax for `#{Regexp.quote(str... mrkn (Kenta Murata)

01:06 AM Ruby Misc #20191: Deprecate magic encoding comment

We should investigate the real-world application codebases instead of gems on rubygems.org.
I guess there can be unexpectedly many scripts in non-UTF8 encoding historically, such as EUC-JP and Windows-31J.
If so, your proposal will bre... mrkn (Kenta Murata)

02:58 PM Ruby Bug #5179: Complex#rationalize and to_r with approximate zeros

`Complex(re, im.to_r).to_r` looks good to me if `im` is not `0` or `0r`. `Complex(re, im.to_i).to_i` is also OK for me in the same manner.
`Complex(re, im.to_f).to_f` cannot resolve the problem the current `to_f` holds. I don't have... mrkn (Kenta Murata)

03:17 AM Ruby Feature #19843: Promote bigdecimal as bundled gems at Ruby 3.4

@hsbt I agree with you. I've wanted to make bigdecimal a bundled gem for a long time but I didn't have much time to work for it. Thank you very much. mrkn (Kenta Murata)
