Perhaps a simpler example for the most basic use case could be 
added near the top. In the heat of solving a problem, 
encountering two pages of theory and explanation for something 
the usage of which should be simple might be discouraging.

Basically, something like:

writeln((checked(5) + 7).get); // 12
writeln((checked(10) * 1000 * 1000 * 1000).get); // Overflow on 
binary operator
