By the way, to rephrase my point - "less time on code readability and more
on abstraction (using maths)". I realize it may not have been clear.
I just see sooo many publicly traded computer companies post financial
losses due to soaring infrastructure costs in their K-8 and K10 reports via
SEC, and I can't help but wonder sloppy "readable functional coding" like
this is to blame.
