Just adding @TypeChecked will bring about compile time system resolution. The sort checker will try to find a process printLine accepting a String over the MyService class, but can't discover one. It's going to fail compilation with the following information:

Assignments normally permit a variable to carry different values at unique instances for the duration of its daily life-span and scope.

The objective is to implement referential transparency, i.e. features that do not depend upon the point out of some variable(s), but make exactly the same outcomes for the offered list of parametric inputs at any point in time.

Modern day packages in other languages also frequently use identical tactics, although fewer rigorous, and only in selected sections, to be able to decrease complexity, Commonly along with complementing methodologies such as facts structuring, structured programming and item orientation.
