Hello Andrew, Tuesday, November 6, 2007, 10:55:58 PM, you wrote:
for me, abstraction is anything that i want to be an abstraction. i just write code in the close-to-natural language and it becomes Haskell program when appropriate syntax applied.
Well, in my experience, figuring out just the right abstractions to use
i don't think about abstractions, just using top-down approach. for me, FP benefit is that when you see that some two things are similar - you can factor out this similarity. in OOP, you should translate it into some class interface, in Haskell you just define parameterized code/data and it works. selection of good abstractions based on these two criteria: 1) factoring out common parts and 2) existence of natural description of the factored part. if i don't see natural description, i can slightly change the factored part -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
