# This check reports blocks with a cyclomatic complexity metric score that is higher than the threshold. The cyclomatic complexity metric counts
# the number of linearly independent paths through the code. This is basically the number of the following statements + 1:
#
# * +if+
# * +else+
# * +unless+
# * +while+
# * +until+
# * +for+
# * +rescue+
# * +case+
# * +when+
# * +and+
# * +or+
#
# ==== Applies to
#
# * blocks
