2006-10-22 Object Oriented Perl

I started reading Object Oriented Perl by Damian Conway. I had mooched the book based on a recommendation by SuShee. ¹

One thing I can say is that chapter two with a quick tour of Perl is clearer than any other book I have read in explaining some of the muddy issues in Perl:

the difference between arrays and lists
the use of references and the arrow operator
the square brackets and curly brackets for array and hash references
some more esoteric syntax such as hash slices and calling a subrouting using &foo in order to pass it the current parameters
the book also makes clear that the parameter array is aliased so you can modify variables in the calling environment, which is something I somehow learned in passing

As I recently said on #emacs, more or less:

*kensanata**
I must confess that in order to get stuff done, I still use the arcane ugly hairy and cryptic language of our forefathers, *P E R L* !!!

Well. I don’t log IRC, so this is entirely reconstructed.

After reading Conways book and some intense studying and thinking I was able to make my own mini-framework for OO Perl programming. I then discovered an almost exact copy on CPAN: Class::Base by the guy behind Template Toolkit. I use that instead now.

Class::Base

Are you considering an OO rewrite of oddmuse? 😃

I still cling on to Perl. I gave python a shot but it just did not feel natural.
