Did you measure the difference in memory usage?
I'd expect it to be small because each Ruby::Box has pretty much a cop... Eregon (Benoit Daloze)

It does, it is determined at parse time. Break is a syntactic construct.

02:01 PM Ruby Feature #21998: Add {Method,UnboundMethod,Proc}#source_range

I discussed this in detail with @mame and @matz.
@mame (to reply here too) what I meant is using Prism with the `Method|UnboundMethod|Proc` and the `source_range` to find the Prism node, and then compute the max end offset by walking th... Eregon (Benoit Daloze)

01:54 PM Ruby Feature #21795: Methods for retrieving ASTs

I discussed this in detail with @mame and @matz.
One observation from me is the addition of `Ruby::Node` (which duplicates a very large part of the Prism Ruby API, >100 classes) is mostly motivated from using `node_id`, because reusin... Eregon (Benoit Daloze)

01:42 PM Ruby Feature #21962: Add deep_freeze for recursive freezing

At the meeting @matz said he was positive that `deep_freeze` is "freeze but recursively".
More precisely:

zenspider (Ryan Davis) wrote in #note-5:

It would do `/regexp/ === exception`, which is not useful but consistent.
