I still believe that it's a compatibility issue and not a feature request or so. Could the ticket be reopened?
----------------------------------------
Bug #18767: IO.foreach hangs up when passes limit=0
https://bugs.ruby-lang.org/issues/18767#change-98098
* Author: andrykonchin (Andrew Konchin)
* Status: Rejected
* Priority: Normal
* ruby -v: 3.0.3
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
`IO.foreach` behaves in an unexpected way in a corner case when passes 0 as a limit parameter. It never stops and hangs up.
```ruby
IO.foreach('file.txt', 0) { |s| p s }
""
""
""
""
""
""
""
""
""
""
```
Expected behavior - to raise ArgumentError "invalid limit: 0" like it does the `IO.readlines` method.
I observe this behavior on 2.6, 2.7, and 3.0. Didn't check on 3.1 and master though.
