I had an employee, who was the only one I had to actually fire..set him
a project, did it in perl, ran slower than almost anything else, and
after 6 months still didn't work. Found out he had being writing a
collaborative science fiction book online most of the time.
Another guy picked it up, had it done in bash in 10 days, at about 1/4
the length, and ten times the comprehensibility, tho still a wee bit slow.
So we looked at the worst bits and did them in C.
I suppose that it was that instance that cemented in my mind the firm
conviction that anyone who thinks PERL is great, is probably a total
wanker, and that includes the guy who wrote it. ;-)
Sadly it does exist on my system because some bloody class library
installation script was written in it.
