I have just taken over 3 Perl scripts (among other things), which has been written by external consultants in the project I am involved.
The 3 scripts aren't using the strict pragma, which is pretty weird, since the people whom developed these are also coding VB.NET in, which you use the pragma 'Option Strict On' to have somewhat the same feature.
The second thing I found troubeling was the extensive code redundancy in the scripts, instead of writing a module the scripts have all be copy-pasted from each other.
Well I guess we need more 'use strict;' Perl t-shirts in the streets...
Briac Pilpre and I came up with a t-shirt design along those lines a year and a half ago.
