use Perl

So far I published more two articles at OnLAMP:

• Boolean operators
• The // operator

and got to complete three drafts for the next ones:

• Negated operators
• The conditional operator
• Range operators

I would appreciate that interested people read them and point mistakes and improvements to be done.

P.S. Yeah, sadly I know that some links at OnLAMP are wrong or missing. But I am afraid that MT changes URL again if I try to update the articles. I don't know what is worse.
