List of Dynamic Arrays
If I wanted to create a DList (or any similar data structure) of multiple integers, how would I accomplish this? I want to write something like `DList!int[]()` but the best I can do for now is a format such as `DList!(Tuple(int, int))()` which confines me to a fixed number of integers.
Unpacking Slices
Is there any shortcut for unpacking slices like I'd want to do in a scenario like this? `info = readln.strip.split;` `string a = info[0], b = info[1], c = info[2];`
Predicates Within Strings
Could somebody explain or point me to documentation that helps to explain the usage of strings in predicates? My main question is how D infers the omitted variable specifications given otherwise - for example: `filter!(a => a < 3)(arr);` and `filter!"a < 3"(arr);` produce the same result.
Inclusion of Parenthesis on Certain Functions
I'm currently learning D right now, and I was wondering why certain functions like std.stdio.readln can work both with and without parenthesis for the function call. I've tried looking through the documentation but can't find an explanation for why you can use it without parenthesis.
