__NOTOC__
=Description=
When the number of nested branches or loops increases, the source code is less readable. This warning is controlled by a complexity threshold preference.

=Example of violation=
<e>if a > 0 then
	from j = 1 until j >= s loop
		from k = 7 until k < 0 loop
			if enable_check = True then
				foo (k, j-1)
				if log_level = 3 then
					foobar
				end
			else
				bar (2 * j)
			end
			k := k - 1
		end
		j := j + 1
	end
end
</e>

=Recommendation=
Encapsulate some of the inner branches or loops into a reusable routine.

In the example, it can simply be:
<e>if attached a_local then
	a_local.do_something
end
</e>
