It's obvious that the reason that he is recommending Forth
over all other languages is that he knows no language that
is higher-level than Forth.  And he finds it too difficult
to learn another language.

If a hammer is the only tool that you have, then you use
a hammer for everything.

How would these tasks be done with a hammer?

Using Gauche Scheme:

Write a function that accepts a vector (1-dimensional array) of
16-bit numbers and replaces each number with its difference
from the average.

(use gauche.uvector)
(use gauche.collection)

(define (relativize vec)
  (let ((avg (round->exact (/ (fold + 0 vec) (s16vector-length vec)))))
    (s16vector-sub! vec avg)))

(define my-vec (s16vector 0 1 2 3 4 5 6 7 8 9))
(relativize my-vec)
my-vec
 ===>
#s16(-4 -3 -2 -1 0 1 2 3 4 5)


Take a string that contains numbers separated by semicolons or
commas and convert it to a list of numbers.

(map string->number (string-split "2,3.14;5.8,9" #/[,;]/))
 ===>
(2 3.14 5.8 9)
