+# How Ruby can do what you don't expect
+
+Ruby is a very clever language. It will take the code you've written and do it's best to make sure it runs. Take for example the following method call:
+
+```ruby
+method_one('Hello', param_two: ' world')
+```
+
+That looks simple enough as it takes two arguments, one positional and one keyword. Now, lets take a look at what the method is actually doing:
+
+```ruby
+def method_one(param_one, param_two)
+    p param_one, param_two
+end
+```
+
+Interesting. At first glance it might appear that this method would print `Hello world`, but there is a subtle difference between how the method has been defined and how it is called. Let's see what it actually outputs:
+
+```ruby
+"Hello"
+{:param_two=>" world"}
+```
+
+So what is going on here? Well, it's because when we call `method_one` we are incorrectly assuming that `param_two` is a keyword argument and are providing the name alongside the value. This is where Ruby tries to be clever as it transforms that into the hash `{:param_two=>" world"}`, which is not what we were expecting. There are a few ways you can deal with this, but the one this post is about is adding a double splat nil to the end of the list of arguments.
+
+# Double Splat Nil
+
+`**nil` might look a bit strange if you haven't seen it before, so lets break it down. A double splat (`**`) is used to indicate that you are expecting a quantity of keyword arguments to be provided when a method is invoked. For example:
+
+```ruby
+def double_splat(**args)
+    p args
+end
+
+double_splat(arg_one: 123, arg_two: 'Four Five Six', arg_three: 789)
+```
+
+That prints out the following hash:
+```ruby
+{:arg_one=>123, :arg_two=>"Four Five Six", :arg_three=>789}
+```
+
+This has loads of uses, but as we've already seen the conversion into a hash can have unintended consequences. That is where `**nil` comes in. This tells Ruby that we are expected no keyword arguments when this method is called. Let's use this to write a version of `method_one` that doesn't accept keywords:
+
+```ruby
+def method_two(param_one, param_two, **nil)
+    p param_one, param_two
+end
+```
+
+Now, what happens if we call it with the unexpected positional argument?
+
+```ruby
+method_two('Hello', param_two: ' world')
+    => no keywords accepted (ArgumentError)
+```
+
+Success! Now, we get an error raised saying something has been called with a keyword when it shouldn't have been which means we don't have to deal with unexpected hashes.
