This type class should be used to indicate a partial function

If your functions make use of partial functions which use this annotation, you have the following options:

1. For application developers: declare an instance of this type class, to indicate that you are willing to accept the use of partial functions globally.
2. Use the partial function to selectively run partial functions.
3. For library developers: pass the Partial constraint onto your users.
