Rebol (<a href="http:&#x2F;&#x2F;www.rebol.com" rel="nofollow">http:&#x2F;&#x2F;www.rebol.com</a>) and subsequently Red (<a href="http:&#x2F;&#x2F;red-lang.org" rel="nofollow">http:&#x2F;&#x2F;red-lang.org</a>) are great languages whose purpose is to eliminate the needless complexity in software engineering. For example; one can write a Rebol parser in 10 lines of Rebol code!
