1 #lang no-vert-bar🔗ℹ

A racket lang-extension that reads | as a normal character.

It takes another language as an argument, so that #lang no-vert-bar racket is a language like racket but without the special behavior for |.

#lang no-vert-bar racket

(define (P-A|B P-A P-B P-B|A)
  (* P-B|A (/ P-A P-B)))

(define (|| a b)
  (or a b))

(define |0>
  (vector-immutable 1 0))
(define |1>
  (vector-immutable 0 1))

These all treat the | like it was any other character, so that it doesn’t interfere with how you name your identifiers.

2 #lang no-backslash🔗ℹ

#lang no-backslash

package:no-vert-bar-lang

A racket lang-extension that reads \ as a normal character.

Just like with no-vert-bar, #lang no-backslash racket would declare a language like racket but without the special behavior for \.

#lang no-backslash racket

(define (/\ a b)
(and a b))

(define (\/ a b)
(or a b))
