By one of those ironies that make life interesting
Wojtek has chosen a bad example. In my Subsystem Lib
almost all the numerical stuff is procedural EXCEPT
the integrators and root finders.
In contrast ALL the mathematical stuff in Subsystem Algebra
is o-o.
However I firmly believe that procedure type are sometimes the
simple and direct solution to a problem and should be kept.
Just ignore people who call them obsolete, they are not.
This reminds me of discussions about the merits of recursion
verses iteration. Some problems require recursion, most in my
area of work are simpler with iteration. I would not want
to work in an environment (FORTRAN IV or Lisp) that mandated one
or the other.
