Hi everyone. I think for the moment I will agree that it would bring more pain to allow circular imports in Go than it would solve problems. One of the most convincing arguments I have read here so far is that it would probably cause many design flaws all around and make many packages very hard to maintain.
I thought about suggesting allowing them in internal package but I finally don't think it's worth the efforts needed to implement that. Thank you all for your answers. Anyway if you guys have other thoughts on the subject, I'm still thinking about it so I'd like to hear them! :) Le dim. 2 déc. 2018 à 08:56, 'Axel Wagner' via golang-nuts < golang-nuts@googlegroups.com> a écrit : > Anecdote: A (large) Java project I worked on ran into trouble with cyclic > dependencies so often, that they started introducing conventions like > "classes under directory X are not allowed to import classes under > directory Y (but vice-versa)", effectively emulating Go's prohibition of > cyclic imports by convention.
