Functional programming in D and some reflexion on the () optionality.

[Dejan Lekic]

You do not seriously expect D to copy exactly how Haskel (or any 
other similar declarative langauge) treat functions? Does it 
really have to be an exact copy? I am not trying to defend D 
language designer(s) here, just trying to say that D should have 
own style, if there is sense behind it, it does not necessarily 
have to conform 100% to any paradigm.

The main reason for me to start using D 10 years ago was the 
obvious PRAGMATIC design of the language. I did not start using 
it because of (possible) functional orientation. Actually, I 
would probably turn my back on D if I saw it promotes declarative 
style more than imperative.

I think the current mix of both worlds is the best direction for 
D.
