Reports chained calls that can be simplified with the safe navigation operator (&.). A group of chained calls is a common pattern to check for nil in each call component.

Example:

# Bad practice
if user && user.profile && user.profile.thumbnails
end

A quick-fix is available to simplify the expression with &.. After the quick-fix is applied, the result looks like this:

# Good practice
if user&.profile&.thumbnails
end
