Dicebot:
While you can do this:
void foo(in @(int a, int b, int c}) {...}
auto result = arr.map!foo;
I believe it is dangerous misfeature and I don't want to see
this in D. Sorry :(
Why do you think it's a dangerous and a misfeature? I think you
are misaken.
It's present in most functional languages, with slight syntax
differences.
The problem is that it's hard to explain how much nice a language
feature is if you have not used it extensively in some language
:-) So I suggest you to try to write some functional code that
uses plenty of tuples. You will see how commonly useful is what I
have written :-)
A similar program in Haskell:
foo (a, b) =
show a ++ " - " ++ show b
lst = [(10, 20), (30, 40)]
main = do
print $ map foo lst
Output:
["10 - 20","30 - 40"]
And Haskell is regarded as one of the safest languages :-)
Similar code is possible in F#, OCaml, Scala, etc.
