lib/syntax_tree/node.rb

Overview

ArgsForward represents forwarding all kinds of arguments onto another method call.

def request(method, path, **headers, &block); end

def get(...)
  request(:GET, ...)
end

def post(...)
  request(:POST, ...)
end

In the example above, both the get and post methods are forwarding all of their arguments (positional, keyword, and block) on to the request method. The ArgsForward node appears in both the caller (the request method calls) and the callee (the get and post definitions).
