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
