[ruby-core:121555] [Ruby Misc#21100] DevMeeting before RubyKaigi 2025

[jeremyevans0 (Jeremy Evans) via ruby-core]

Issue #21100 has been updated by jeremyevans0 (Jeremy Evans).


* [Feature #21216] Implement Set as a core class (jeremyevans0)
  * I propose to implement Set as a core class.
  * I have a pull request that adds a value-less `st_table` (named `set_table`), for a 33% memory savings.
  * Core Set speeds up the majority of Set methods, with 47% of benchmarked cases being at least twice as fast.
  * Open questions are:
    * How to expose this in the C-API.
    * Whether to share types with `st.c` (currently, all types are renamed from `st_*` to `set_*`).
    * Where the code should live (potentially `st.c` if types are shared).
    * Where to use this internally (potentially, fstring table and proposed refinement call cache).

[byroot (Jean Boussier) via ruby-core]

Issue #21100 has been updated by byroot (Jean Boussier).


* [Feature #21219] `Object#inspect` accept a list of instance variables to display (byroot)
  * Redefining `#inspect` can be important to avoid secret leak or to avoid very large `inspect` representations
  * Right now implementing a custom `#inspect` isn't as simple as it seems (e.g. circular references, object_id, etc)
  * Should we make it easy to keep the default `#inspect` but hide some instance variables?

Issue #21100 has been updated by ko1 (Koichi Sasada).


* [Feature #21262] Proposal: `Ractor::Port` (ko1)
  * Considering with [`Channel`](https://bugs.ruby-lang.org/issues/21121), `Port` concept seems better for me.
  * I found that `take`/`yield` is so difficult to implement correctly and efficiently enough to support `Ractor.select` in 4 years, so I'm voting to remove them.
