Aggreed. 
But there is nothing wrong with making the syntax user friendly, or am I
totally missing what perl is?
Why do we have qw()? 
Why do we have "=>" as an alias for comma (at least most of the time)?
Why doesn't perl force us to use paranthesis when calling functions?
etc. etc.

Which array?

In general we can say "data mining" I guess. It will be great more people
will switch to perl from these areas and I think perl is the perfect
choice. Genome people are already using perl in some areas. 
By the way any decent implementation of  analysing their web logs, or
summarising their customer segments, or reviewing survey results will
require tools such as SVD, FFT and other similar transformations.

Baris.
