 - Use `static` closures as much as possible to reduce the probability of creating circular references by capturing `$this` as it can lead to memory root buffer exhaustion.
 - Remove keeping intermediary values of a deferred `Sequence` that is referenced by no one.

 - Using `string`s or `int`s as a `Map` key type and then adding keys of different types was throwing an error.

 The `Fold` monad is intented to work with _(infinite) stream of data_ by folding each element to a single value. This monad distinguishes between the type used to fold and the result type, this allows to inform the _stream_ that it's no longer necessary to extract elements as the folding is done.
 
 An example is reading from a socket as it's an infinite stream of strings:

 # `State`
 
+??? warning "Deprecated"
+    `State` is deprecated and will be removed in the next major release.
+
 The `State` monad allows you to build a set of pure steps to compute a new state. Since the initial state is given when all the steps are built it means that all steps are lazy, this use function composition (so everything is kept in memory).
 
 The state and value can be of any type.
