( #3333=superdoc: print w/replies, xml ) Need Help??

I did warn you that I was going to talk as if I understoof FP :) Thanks for making allowances and not making capital from that gross misassumption.

I remember when I first tried to learn SmallTalk. I was trying to get to grips with it at home whilst continuing to write hardcore C + assembler(device drivers) for 10 hours a day at work. I never quite "got" SmallTalk until I was commisioned to write a "First Introduction" course, and got to spend a month completely immersed in the language. Only then did the penny drop. It's still my all-time favorite language, although I have considerable reservations about it's use for commercial, multi-programmer projects.

It seems obvious that in order to get the usefulness of FP, I will need to spend a similar amount of time, or more, completely immersed in Haskell or one of the other modern implementations of FP. That is going to be a hard thing to pursuade myself to do. I have several ongoing projects in Perl and D that I want to bring to a close first.

**This is (mostly) a joke**.

A like your Fishing Pole analogy--a lot--but both times you brought it up, I couldn't help myself wondering why I (you) would want to use Perl to write FP?

I guess I will need to reach the point where writing code in the FP style no longer seems an "unnatural practice" before I will be able to answer that question.

When I do try to do something in Haskell, I still find myself having to spend a ratio of like 10 or 20 to 1 reading the docs and example code to time actually coding. I keep wanting to use loops, conditionals and temporary variables and insert a few prints to debug the code when it just sits there and does nothing. I started playing around with the famously elegant Haskell definition of the QuickSort algorithm. Neat, but is it ever slow and inefficient.

So thanks for your articles and the time you've taken responding to my questions and doubts. I'll shut up now and let you get on with your explorations of FP in Perl unhindered.
