+        return function(value)
+            return {
+                type = "MyAction",
+                value = value,
+            }
+        end
+
+    And then when you check for it in your reducer, you either use a constant,
+    or type out the string name:
+
+        if action.type == "MyAction" then
+            -- change some state
+        end
+
+    Typos here are a remarkably common bug. We also have the issue that there's
+    no link between reducers and the actions that they respond to!
+
+    `Action` (this helper) provides a utility that makes this a bit cleaner.
+
+    Instead, define your Rodux action like this:
+
+        return Action("MyAction", function(value)
+            return {
+                value = value,
+            }
+        end)
+
+    We no longer need to add the `type` field manually.
+
+    Additionally, the returned action creator now has a 'name' property that can
+    be checked by your reducer:
+
+        local MyAction = require(Reducers.MyAction)
+
+        ...
+
+        if action.type == MyAction.name then
+            -- change some state!
+        end
+
+    Now we have a clear link between our reducers and the actions they use, and
+    if we ever typo a name, we'll get a warning in LuaCheck as well as an error
+    at runtime!

+
+	memoize creates a function as a wrapper that caches the last outputs of a function.
+
+	This is useful if you know that the function should return the same output every
+
+	time it is run with the same inputs. The function should only return an output, and
+
+	not have any side effects. These side effects are not cached.
+
+
+
+	Without memoize's caching, even though the function ouputs the same values, the
+
+	memory locations of the values are different; tables made in the function, even if
+
+	they have the same values, won't be the same tables.
+
+
+
+	memoize only caches the last set of inputs and ouputs. This means that it is only
+
+	helpful when the function is likely to be called with the same inputs multiple
+
+	times in a row. This is the case with most Roact use cases.
+
+
+
+	Note that memoize only does a   ** shallow check on table inputs **   . This means
+
+	that if the same table is input but the elements of the table are different then
+
+	it will be assumed that the table has not changed.
+
+
+
+	In addition to all the previous warnings, memoize strips trailing nils. This means
+
+	that if foo is a memoized function and we call foo(), then foo(nil) will return a
+
+	cached value. This is opposed to how print handles input. print() only outputs a
+
+	new line, but print(nil) outputs "nil". This is because varargs can detect the
+
+	number of arguments passed in. So, be careful when using memoize with varargs.
+
+	Trailing nils will be stripped.
+
+
+
+	The wrapper can take any number of inputs and give any number of outputs.
+
+	Leading and interspersed nils are handled gracefully. Trailing nils on the input
+
+	are stripped.
