I don't care about the speed that much. Clarity of code is more important.
And I agree how Baruchel's tco module needs to be used, doesn't seem
very helpful in that respect. I wouldn't call it obnoxious, cause I
can appreciate the mathematical elegance behind it, but my impression is
that understanding what is going on, requires a back ground knowledge
that is generally not expected. So using this would probably be good for
job security but wouldn't be fair to my colleagues.
