1. Specific answer for this case:

As I said in the postscript,

"""I like the concept of reduce, but
not the syntax, and that is the reason why 
I *never* use 'reduce' in my programs."""

I find the current syntax little readable. 'reduce' does not seems
very abstrac to me.

2. General answer.

No, I don't like abstraction for the sake of abstraction.
I like abstraction when actually it is useful and help
to explain/unify difficult concepts. I HATE abstraction
when it is intended to complicate simple things or when
you don't need it. On the other hand, excessive simplification 
is also to be avoided:

Things should be made as simple as possible, but not simpler.
