Desired functionality.
Circular dependency bugs are easy to introduce and can be hard to detect and troubleshoot. Sometimes everything works fine, but in a few cases I've had module imports show up as undefined at runtime. Last time it happened, it was only in AOT mode, so I didn't catch it initially.
It would be helpful if the CLI included a plugin that warns you if circular dependencies are detected and logs the modules that are part of the cycle.
Mention any other details that might be useful.
I used this plugin and it found several issues in my project.
However, I couldn't configure Webpack to use the plugin without ejecting the config, and I'd rather not have to do that each time I need to debug an issue like this.

I'll have a look. I agree it's a difficult to debug issue and that we should add a plugin if it helps and has no unexpected side effects.
