But in the terms of technical precision, what happens when I create new instance of class? class a { } class b { a InstanceOfA; InstanceOfA=new (); //which ...
I want to make all types that are instances of Enum and Bounded also an instances of Random. The following code does this and should work (with the appropriate extensions enabled): import System.Random instance (Enum r, Bounded r) => Random r where randomR (hi, lo) = inFst toEnum . randomR (fromEnum hi, fromEnum lo) where inFs...
