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.

say, i want to display archive listing. i write:

dir <- readDir archive
listing = map listfile dir
print$ [header]++listing++[footer]

then i write definitions of readDir, listfile and so on in the same
manner
