[Jprogramming] FW: A simple function

[Jose Mario Quintana]

I, for one, love 0.  However, cap does something: "[: signals error on any argument."  Yet, the behavior of a fork is exceptional when a cap is at the beginning, then the middle verb acts monadically instead of dyadically.  It is this apparent “spooky action at a distance” that bothers some functional programmers.

The controversy is neverending, some prefer to avoid @, some [:, and others none.

Here is my attempt to make [: lovable.  You love 0, don’t you?


   g     When f is [: in the diagram at left
  / \    the left branch disappears and you
f   h   get the diagram below: “I do nothing”
|   |   [: is like “I am nothing” 0 .
y   y

   g
    \
     h
     |
     y


     g      Also here when f is [: the left
    / \     branch disappears and you get
   f   h    the diagram below:  “I do nothing”
  / \ / \   [: is like “I am nothing” 0 .
x  y x  y

     g
      \
       h
      / \
      x  y
