Hi there

First things first, I am a big fan of OOP in general. However I do agree OOP is not always the best choice. Since Perl promotes the idea of TIMTOWTDI (There's more than one way to do it), we have plenty of options to pick from. I have come across many Perl haters in the past complaining about lack of proper OOP support in Perl. With the introduction of postmodern object system for Perl, Moose, we finally had structured OOP support. I must confess I prefer Moo which is known as minimalist object orientation.

Fast forward to now, Curtis Poe joined hands with other Perl masters and came up with Corinna. It is proposed to be part of core Perl soon. I can't wait for that to happen. I sincerely applaud the efforts of each and every contributor of Corinna. I beleive it will be the best addition to the Perl core in recent times. I am confident it will be the highlight of the future Perl7.

In the last week edition of the weekly newsletter, Gabor reminded me that I forgot to celebrate the special 512th edition. What a shame, I missed the opportunity. I blame my busy routine for the missed opportunity. I am looking forward to my personal 100th edition of the weekly newsletter. This is the 79th edition for the record, not far off from the target.

Happy to see, the COVID-19 situation in India is getting better. I pray to ALLAH s.w.t for the complete protection from COVID-19. Please look after yourself and your loved ones.

To all our readers in the UK, enjoy your bank holiday with the weekly newsletter.
