Description
What I want to do put a mock around around existing instance so I that I verify that the methods are called
IFoo foo = GetFoo();
var mock = new Mock( foo );
mock.Setup(....)
The only way I can see to this is to implement IFoo myself that wraps the foo instance and then do
new Mock(foo)
is there some other way to do this?

Research direction
The issue names Mock, IFoo, and an existing IFoo instance; start by reviewing Moq's Mock construction and interception behavior. Determine whether an existing interface instance can be wrapped while preserving method verification, and define completion as either a supported usage path or a clearly scoped feature with tests.
