He also forgot that it returns far less error messages since it just
assumes "something" whenever the input is unintelligible or if the
requested feature is not what the programmer should want, speed wise.

Oh, and it is much much faster too. For example numeric data does not
use those horrible expensive string math routines for exact precision,
it has full hardware floating point support instead, so it will actually
use your math co-proc (if you have one). These accounting bureaucrats
really shouldn't worry, at that speed one can create many more results
and one will probably be right someday.
