The scenario is similar to the "Data Exchange Definition" where you can specify the number of a codeunit to implement a functionality (see "Data Handling Codeunit" or "User Feedback Codeunit").
In these cases a statement like this would be useful:
IntA := INTERFACE.GETINSTANCE(CodeunitID);
Where IntA is a variable of type interface and CodeunitID is the number of a codeunit implementing the IntA interface.

I realize that the use of interfaces is not yet widespread at the moment, however I feel the absence of a statement like this to be a rather strong limitation.
