Perl... it still makes me shudder. I never got to grips with it.., and it was around 2003 when I was looking at an enormous script written by someone else and thinking... christ!
I know where you are coming from. If I don't add the comments, I will forget how it works, never mind anyone else.
Perl, Pascal, C, VB .... They all make me shudder if they aren't documented. But perl. A hash of a hash of a hash ... c'mon!!!! Without comments!!! It's a nightmare.
I have to admit ... when I think of the term "Multidimensional Hash", this is the last thing that comes to my mind!
Hrmmmm...... What does come to mind ....
