    v1 v2  
    99  * Implement a declarative IO system. 
    1010  * Don't be afraid to use extensions (although we should probably establish a list of which ones are "safe" and which are not). 
     11  * When there is more than one possible instance of a type class for one data type, use newtype wrappers for all of those instances (no instance for the unwrapped version). 
     12  * Don't worry about numerous type classes as long as they are small.
