[ruby-core:91309] [Ruby trunk Feature#5653] "I strongly discourage the use of autoload in any standard libraries" (Re: autoload will be dead)

[rafaelmfranca@gmail.com]

Issue #5653 has been updated by rafaelfranca (Rafael França).


I think you missed an important point here. Like @fxn said above:

> First and foremost, I'd like to be very straightforward saying that if Kernel#autoload is killed tomorrow, that would be fine with me. I'd shutdown Zeitwerk and Rails 6 plans without regrets.

So Rails team is not forcing anything. If Matz decide remove `autoload` we would gladly change Rails to use something else.

Right now is exactly the best time to make that decision since `Zeitwerk` is pretty new and we still didn't bet even more in `autoload`. Making this deciding this two or three years from now would make it even harder since more Rails applications would be using `autoload`.

That was my initial reason to comment in this thread. Give Matz one more data point on what problems autoload solves that other alternatives doesn't and ask feedback if we should or should not bet more in `autoload`.

There is no need to be sad ;)

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.
