-Be aware that this wrapper is stateful, storing the state machine's history in an internal array. This is contrary to what a simple non-interpreted state machine does, which is fully pure and doesn't store any internal state. 
+Be aware that this wrapper is stateful, storing the state machine's history in an internal array. This is contrary to what a simple non-interpreted state machine does, which is fully pure and doesn't store any internal state.
 
 This conflicts with the way that `transition` works (which is pure) since we're augmenting its behaviour to store its result. But this was an acceptable drawback for my use case, and I may consider extending this library with a `pure` version in the future.
