09:39 PM Ruby Feature #16848: Allow callables in $LOAD_PATH

BTW, the contract could be to return a file handle (which could be a StringIO) or `nil`. fxn (Xavier Noria)

03:13 PM Ruby Feature #16848: Allow callables in $LOAD_PATH

02:07 PM Ruby Bug #21830: Ruby::Box and Kernel#require

Just in case it matters, let me also add that it is assumed that `Module#autoload` invokes `Kernel#require` as introduced in [cd465d5](https://github.com/ruby/ruby/commit/cd465d552c3a00341f4cb7f1d7a793d0ebcb6cde).

07:29 PM Ruby Feature #21800: `Dir.scan` to list directory entires with their type

Hi there!
@byroot knows this, but for anyone reading, Zeitwerk essentially scans the file system and sets autoloads for the expected constants.
This feature is going to be great. As in the general case described in the issue descriptio... fxn (Xavier Noria)

11:07 PM Ruby Misc #21154: Document or change Module#autoload?

BTW, I do not know if you know it, but while I started working on Zeitwerk to fix autoloading in Rails, I changed my mind in the mid of it and decided to do something more generic that supports multiple autoloaders in the same process ma... fxn (Xavier Noria)
