Subject: [ruby-core:103343] [Ruby master Bug#17789] Incompatible behavior of Enumarator::Lazy#with_index
Date: Fri, 09 Apr 2021 11:03:56 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-91434.20210409110355.51536@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-17789.20210409084606.51536@ruby-lang.org
Issue #17789 has been updated by soudai_s (Soudai Sasada).
It means It's no longer compatible with 2.6 or under, isn't it?
Thank you for quick reply!
----------------------------------------
Bug #17789: Incompatible behavior of Enumarator::Lazy#with_index
https://bugs.ruby-lang.org/issues/17789#change-91434
* Author: soudai_s (Soudai Sasada)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin20]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
this method ignores the block passed to it, but this behavior looks different from the Enumerator (super class).
```
$ ruby -e '%w(a).lazy.with_index { |s, i| puts "#{s} => #{i}" }'
a => 0 # Expected, but doesn't actually print anything
```
After confirmation I found #16414 but this behavior was not fixed and the doc in the modified source code states: "If a block given, iterates the given block for each element".
Is this behavior intended?
