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.
