#!/usr/bin/env ruby
# Cyclomatic complexity analyzer for Ruby methods.
#
# Counts the number of linearly independent paths through a method by
# starting at 1 and adding 1 for each decision point:
#   - conditionals : if, elsif, unless (including postfix forms), ternary ?:
#   - loops        : while, until, for (including postfix forms)
#   - case/rescue  : each `when` clause, each `rescue` clause
#   - boolean ops  : &&, ||, and, or
#   - safe nav     : &. (each call may short-circuit, so it's a branch)
