## Intent
Execute Around idiom frees the user from certain actions that
should always be executed before and after the business method. A good example
of this is resource allocation and deallocation leaving the user to specify
only what to do with the resource.

## Applicability
Use the Execute Around idiom when
* you use an API that requires methods to be called in pairs such as open/close or allocate/deallocate.
