I think it's very nice to write as little code as possible,
not to the point where no code at all is needed,but as little as possible.
Recently I read a article about monads in Perl , which made a big impression on me. It expressed some things in a very elegant way. To what extent those things are useful is still an unanswered question for me.
I found myself rewinding on some old Perl presentation and finding about a regex to validate
nested parens,this also was very elegant.
Are there any other articles that describe what is covered in this presentation in a more detailed way ?(in particular Monads).
Have you used Monads in Perl and why would they be useful ?
Have you used functional programming in Perl , to what extent and has it been useful or just a caprice?
