I wouldn't call it a "pretty good case". He argued that writing
*functions* was a bad thing, because the name of a function didn't
provide all the details of what was going on in the same way that
explicitly writing the code inline would do. That seems to me to be a
somewhat bizarre argument - after all, encapsulation and abstraction
are pretty fundamental to programming. I'm not even sure he had any
specific comments about accumulate other than his general point that
as a named function it's somehow worse than writing out the explicit
loop.

It's worth adding a reminder here that "having more options on the
market" is pretty directly in contradiction to the Zen of Python -
"There should be one-- and preferably only one --obvious way to do
it".
