Hi Jerzy,

Thank you for your thorough response. I will archive it and come back to 
it as a reference. As I learn more about FP features (e.g. Monads) I'll 
be able to get more from your description.

But just a quick note:

For me, right now, this makes a world of a difference. I'm experimenting 
with small exercises on Hugs right now.

Yeah, I noticed... ;-)  But I recently learned about a neat workaround:

I have a file called Test.hs and load it with ':l Test'. Then I start 
exprimenting. I make a small change and type ':l Test' again. So it's 
almost interactive, and not excessively akward.

I think I'll learn a bit more using Haskell, and then I'll be in a 
better position to decide where to continue (probably with Haskell at

Well, I merely ask for general impressions and go from there.

Ok. Good to know.

That's why I'm here.  :-)

I have a strong preference for languages with clear, simple models. For 
example, I like C better than C++, and Ruby better than Python. Even if 
something might take fewer lines in C++ than in C, or be faster in 
Python than in Ruby, I like the feeling that I understand what I'm 
doing. And I see elegance in a simple model with few exceptions.

Indeed. I've been pleasantly surprised by how friendly this group has 
been. I've learned a lot already, and now I have a lot of resources to 
continue my exploration of Haskell and FP.

Incidentally, the Ruby community is friendly too. :-)
