Pattern: Missing use of Array()
Issue: -
Enforces the use of Array() instead of explicit Array check or [*var].
# bad
paths = [paths] unless paths.is_a?(Array)
paths.each { |path| do_something(path) }
# bad (always creates a new Array instance)
[*paths].each { |path| do_something(path) }
# good (and a bit more readable)
Array(paths).each { |path| do_something(path) }
