 Signals are basically an encapsulated variable (or state node), which can provide getters/setters against that variable. The reason for this is (in short) is that Signals can act as a means of knowing when to trigger change detection intelligently in the component tree. Previously, ZoneJS would just hook all over the place and fire change detection loads of times even when it's not needed. The result is synchronous, performant, as-needed change detection, making application state management less magical and more transparent. 

 ```
 const myVariable = 4; 
 const mySignal = signal(myVariable); 
 console.info(mySignal()); // 4
 mySignal.set(5);
 console.info(mySignal()) // 5
 ```

 But the problem is a Signal must be invoked to get at its variable. Because TypeScript treats Signals as function-like, this creates a range of problems when referencing a signal and forgetting to invoke it.
