No description provided.

Fix issues where MaxChainedCallsOnSameLine would report long import and package directives, where a warning certainly isn't necessary.

I've now run on the detekt codebase (with a max of 7 since there are some violations longer than 5) to verify that there aren't any more obvious false positives.

There are still interesting cases (example) with fully-qualified class names which still violate this rule; thoughts on what to do there? I haven't looked into it yet, but I'm not certain whether it will be possible to differentiate those from normal qualified expressions.

I think that we will need to use type solving.

I think that we will need to use type solving.

How would that rule benefit from type solving? Could you please highlight an example?

This was in response to this example of a fully-qualified class name which this rule currently flags. Probably this rule should ignore such cases (although this one can just be imported), but I agree that type resolution is probably necessary to determine whether a chained calls are from a fully qualified class name. I'll open a separate issue to track/discuss that.
