The PR restoring this cop was one day late for 1.30.1.

|===

Checks for useless `else` in `begin..end` without `rescue`.

NOTE: This syntax is no longer valid on Ruby 2.6 or higher.

=== Examples

[source,ruby]
----
# bad

begin
do_something
else
do_something_else # This will never be run.
end
----

[source,ruby]
----
# good

begin
do_something
rescue
handle_errors
else
do_something_else
end
