in thread How does one learn perl programming efficiently - if they do not come from computer science background?

I found that if I got the data structures correct, the code usually flowed. If not, things got messy fast.

This piece of advice reminds me of the following famous quotes from Fred Brooks, Rob Pike, Eric S. Raymond, and Linus Torvalds:

The programmer at wit's end for lack of space can often do best by disentangling himself from his code, rearing back, and contemplating his data. Representation is the essence of programming.

-- from The Mythical Man Month by Fred Brooks

Data dominates. If you've chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming.

-- Rob Pike

Show me your code and conceal your data structures, and I shall continue to be mystified. Show me your data structures, and I won't usually need your code; it'll be obvious.

-- Eric S. Raymond

I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important. Bad programmers worry about the code. Good programmers worry about data structures and their relationships.

-- Linus Torvalds

    I knew the Raymond quote because itís used as a chapter intro in some Perl book or another. I didnít know the others. Good to see them.

    Great quotes! "The Mythical Man Month" should be required reading.
