Scheme of things

  • Article

Programming in Static OO languages for a long time numbs the brain. These languages are designed to be simple and efficient. These criteria not necessary create beautiful languages. In the world of C++, C# our imagination get severely restricted.

Take for example the expression x + |y|. In scheme you can code this as

 (define (addAbs x y)
  ( ( if (> y 0) + -)  x y))

(addAbs 4 -5)

The if expression is very interesting. It actually compares y with 0 and returns a operator (+ or -). Its simply beautiful :)

    Thanls Al :)I never learnt Scheme on its own. I went through SICP http://mitpress.mit.edu/sicp/full-text/book/book.html and picked up bits and pieces of Scheme on the way.SICP is a must read for any SW engineer
