This is an interesting thread but can I urge posters to reply to
[EMAIL PROTECTED]
The Haskell-cafe mailing list is designed for precisely the kind of discussion
in the current thread. But Haskell@haskell.org is a low-bandwidth mailing list
for announcements and the like.
Thanks
Simon

| Mike,
|
| It has affected my Java/C/C++ programming a lot.
|
| 1. I am much more careful how I combine ( inherit, compose, aggregate )
| code because of potential side affects
|
| 2. It has helped to find certain types of bugs in Java code more easily
| that come up because of subtle effects introduced by combining code
| together
|
| 3. It has helped me to write code that is more composable
|
| 4. Haskell has increased my awareness of how important type safety is So
| I use Java Generics more now to enforce more type safety when I can
| (sometimes I am stuck deploying to java 1.4) (I also use C++ templates
| to do the same thing for C++) But these are often feel like hacks
|
| Haskell's type system is a thing of pure beauty haven't seen anything
| quite like it in any other PL (ML and OCAML are as close as I have seen
| but still fall short) and Generics and Templates really can't compare
|
| You really want the compiler to help you out as much it can. Have it
| tell you when you are doing something that you shouldn't be doing.
|
| By the way Mike thanks you just totally cheered me up I guess I just
| needed to sit back and think about what I have learned and how valuable
| it is to me.

| Troy,
|
| As a Java chimp embarking on the Haskell journey myself, I'd be
| interested in hearing about specific ways that learning Haskell has
| changed the way you program Java. How do you employ the "very
| interesting concepts" that you have learned through your study of
| Haskell in your Java programming? Do you employ them at all? _Can_
| they be employed in Java? Has it made you a better Java programmer?
|
| Cheers,
| Mike
