[ruby-core:91213] [Ruby trunk Feature#5653] "I strongly discourage the use of autoload in any standard libraries" (Re: autoload will be dead)

Issue #5653 has been updated by rafaelfranca (Rafael Fran巽a).


@matz when taking in consideration deprecation/removal of autoload I'd like you to consider that Rails built and plan to use a thread-safe code loader based on `autoload`. See https://medium.com/@fxn/zeitwerk-a-new-code-loader-for-ruby-ae7895977e73

Hi,
 
Today, I talked with NaHi about enhancing const_missing to enable
autoload-like feature with nested modules.  But autoload itself has
fundamental flaw under multi-thread environment.  I should have remove
autoload when I added threads to the language (threads came a few
months after autoload).
 
So I hereby declare the future deprecation of autoload.  Ruby will
keep autoload for a while, since 2.0 should keep compatibility to 1.9.
But you don't expect it will survive further future, e.g. 3.0.
 
I strongly discourage the use of autoload in any standard libraries.
 
matz.
